`GENERAL INFORMATION
`Safety
`
`
`
`WARNING
`
`This unit emits ultraviolet (UV) radiation that is harmful to humans.
`Avoid exposure to the direct or reflected output beam. Make certain
`that the appropriate output beam shields and optics are in place prior
`to energizing the unit. All interlocks must be satisfied prior to
`operation; failure to do so may lead to hazardous conditions.
`
`
`
`
`
`1
`
`
`
`CAUTION
`
`The EQ-1500 emits dangerous levels of UV radiation. Even short
`exposures to skin or eyes may cause burns. Ensure that only
`authorized personnel are in the vicinity of source during operation.
`Personnel in vicinity of operating source should wear protective
`eyewear, clothing, and gloves. Lighted UV warning lights and signs
`posted on doors to lab areas may help prevent accidental exposure.

`
`

`
`
`
`WARNING
`
`The EQ-1500 utilizes an internal Class 4 IR laser
`capable of causing severe injury to eyes or skin. Do
`not open or attempt to service this unit. Contact
`Energetiq regarding any problems with the unit.
`
`
`
`
`
`General Precautions
`The output beam from the EQ-1500 should be blocked when not in use with an electronic
`shutter or other appropriate beam blocking device. Due to the absorption of the short
`wavelength light and the possibility of ozone production, the beam should always be either
`directly coupled to a fiber optic cable, or enclosed in an appropriate beam pipe, tube, or
`enclosed space. We suggest purging any beam transport space with dry Nitrogen gas, as this is
`also required for safe operation of the EQ-1500.
`
`The source must be purged with dry nitrogen gas via the nitrogen input connector on the lamp
`head. The unit must be purged for a minimum of 10 minutes prior to operation in order to
`ensure that no ozone is created by residual oxygen inside the unit. It is recommended that any
`beam transport be purged for a similar amount of time.
`
`The EQ-1500 controller must be connected to an appropriate closed-loop water chiller
`system. The water system must be capable of maintaining 0.5gpm at 18°C with a minimum of
`200W cooling capacity
`
`The EQ-1500 source must also be cabled correctly and connected to a socket with a protective
`earth ground prior to operation. Failure to do so may result in an electrical shock hazard.
`
`Refer to the Installation section of this manual (Chapter 3) for details of the facilities
`connections.

`
`

`
`
`
`There are no user-serviceable parts inside the EQ-1500. For any problems encountered during
`operation, please refer to the Troubleshooting section of this user manual. If there is a
`component failure, do not attempt to open the chassis of the EQ-1500.
`
`The EQ-1500 utilizes a quartz lamp containing a high-pressure gas fill. Explosion of the lamp
`and possible injury from flying fragments can occur if the lamp is mishandled. Never attempt
`to remove or replace the lamp. If there is a failure of the lamp, the unit must be shipped
`back to the factory for refurbishment.
`
`Do not open the chassis of either the lamp unit or the power supply unit. Dangerous
`invisible infrared laser beams and hazardous voltages exist inside the units. Opening
`the chassis both voids the warranty and exposes the user to dangerous radiation and hazardous
`voltages.
`
`CAUTION
`
`The EQ-1500 must be operated for its intended use and as
`described in this operating manual. Operation in an un-intended
`manner may result in dangerous conditions.
`
`CAUTION
`
`Use of controls or adjustments or executing procedures other
`than those specified herein may result in hazardous radiation
`exposure.

`
`
`
`Laser Information
`The EQ-1500 uses a patented (U.S. Patent #7,435,982, others pending) laser drive system to
`excite a plasma that radiates in the UV as well as the visible bands. Since the lamp unit
`contains an embedded laser, the EQ-1500 is defined as a Laser Product. However, the drive
`laser does not exit the system.
`
`The parameters of the non-accessible internal laser are given below in Table 1.

`Cover Interlocks
`The EQ-1500 is equipped with cover interlock switches to prevent operation of the source
`without the lamp unit and controller covers in place. Since no user service is permitted, these
`switches are intended for the protection of factory service personnel.
`
`External Interlock
`An external interlock connector is provided for the customer’s use. Any suitable
`normally-open contact can operate the interlock circuit. The unit is shipped with a shorted
`connector which may be used to connect to the user’s interlock circuitry. The interlock circuit
`must not be grounded.

`
`
`
`Energetiq Ex. 2055, page 10 - IPR2015-01362
`
`

`
`
`
`The interlock circuit must be connected to enable the operation of the unit. Should the
`interlock connection open during operation or standby, the source is immediately disabled, and
`all light output from the aperture ceases. The source is then latched off and will not restart
`until the interlock is restored and the lamp manually restarted.

`
`
`Chapter 3
`INSTALLATION
`Installation of the EQ-1500 consists of connecting electrical, water, and gas supplies, and
`connecting the lamp output to the user’s equipment.
`
`Unpacking
`Upon arrival, start by inspecting all parts of the system for completeness and any damage
`incurred in shipping. The EQ-1500 shipping box should contain: 1) EQ-1500 Controller unit,
`1) EQ-1500 Lamp House, 1) Lamp House Signal/Power Cable, and 1) 2m IEC power cord.
`If any part is missing or appears damaged, contact the manufacturer. Do not attempt to
`substitute any parts. There are no user-serviceable parts inside the EQ-1500 Lamp House or
`Controller unit.
`
`The EQ-1500 system is shipped with the laser fiber optic cable already connected between the
`Controller and Lamp House. Use care during installation and operation to avoid creating
`sharp bends or kinks in the cable. Minimum bend radius for the cable is 60 mm (2.4 in).
`
`Facilities Connections
`
`Electrical Service
`The EQ-1500 can be operated from 100–120/200–240VAC, single-phase, 50-60Hz. Power
`consumption is approximately 200VA during normal operation, 300VA during lamp starting.
`
`The EQ-1500 uses a detachable three-wire standard IEC 60320 C13 cord for connection to
`the power source. The cord also provides the connection to the protective earth circuit.
`Exposed metal parts of the EQ-1500 are connected to the protective earth ground via the cord
`and the outlet ground, providing protection against electrical shock. Never operate the EQ-
`1500 from an outlet without a properly connected protective earth ground.
`
`There is no selection switch for line voltage, it is automatically adjusted internally.
`
`16
`
`
`
`Energetiq Ex. 2055, page 20 - IPR2015-01362
`
`

`
`
`
`Cooling Water
`The EQ-1500 requires 1.9–3.8 lpm (0.5–1 gpm) water at a minimum of 0.14 MPa (20 psi).
`The temperature must be held at 18 ± 1 degrees C. The pressure drop at 3.8 lpm (1 gpm)
`through the cold plate is less than 0.07 MPa (10 psi). There are several thermoelectric and
`direct water-to-water chillers that can satisfy these requirements. Tight temperature regulation
`is required for tight regulation of the lamp’s output. If there are any questions or concerns,
`please contact the manufacturer for recommendations or guidance.
`
`The Lamp House water connection fittings are push-to-connect fittings sized for 3/8” O.D.
`tubing. The Controller water connection fittings are 3/8” Swagelok® tube fittings.
`
`The Lamp House and Controller should be connected in series, with the Controller upstream.

`
`
`Purge Gas
`The EQ-1500 requires grade 6 or better nitrogen purge gas. The requirement for purge gas is
`a result of the EQ-1500 lamp’s unique performance and operating principles. The EQ-1500
`
`EQ-1500 Operation Manual Rev 4
`
`17
`
`Energetiq Ex. 2055, page 21 - IPR2015-01362
`
`

`
`
`
`produces UV radiation capable of generating ozone gas when exposed to atmospheric oxygen.
`So first and foremost, the nitrogen purge gas is intended to displace any oxygen in the system’s
`optical chamber. The optics assembly is in direct contact with this purge gas. UV optics are
`quite prone to UV photo contamination. Clean and pure nitrogen from either a dewar or
`research-grade N2 bottle is recommended. Do not use any other purge gas. Usage of
`clean dry air (CDA) may cause damage to internal optical components, and is likely to
`produce ozone gas, which is a potential inhalation hazard.
`
`The fitting is a push-to-connect fitting sized for 1/4” O.D. tubing. The suggested hose to
`mate to this fitting is either Nylon: Shore D 50-70, Polyethylene: Shore D 50-196, or Teflon
`1/4” O.D. tubing.
`
`There is no return fitting for the purge nitrogen. The purge flow normally escapes within the
`lamp unit enclosure, and then to atmosphere.
`
`Optical Interface
`The exit aperture consists of a Newport LH-1-5 1.5” lens mount. This incorporates a 1.563-20
`thread. Optionally, to utilize the full 0.5 NA output of the EQ-1500, this lens mount can be
`removed. With the lens mount removed, the machined mounting holes on the front panel can
`be used to interface to the EQ-1500 to external optics. Figure 7 shows the details of the
`optical interface. See Figure 8. below.
`
`Any beam transport space should be purged with dry nitrogen to prevent the formation of
`ozone from atmospheric oxygen.

`
`
`External Interlock
`The connector is a 2-pin circular connector, Hirose part no. RM12BPE-2PH. It can be
`connected to any suitable dry-contact switch, such as a snap switch for a beam line cover or
`other door switch. The contact should be rated for a minimum of 15mA at 15VDC.
`
`In order for the EQ-1500 to operate, this circuit must be closed. The system is shipped with a
`jumpered connector installed.
`
`Installation procedure
`1. Mount the Lamp House rigidly to either an optical breadboard plate or another
`suitable mounting structure using the threaded holes on the bottom or front of the
`unit. The holes are sized to accept standard ¼-20 optical bench hardware, and spaced
`to be compatible with a standard 1” grid mounting hole pattern..
`2. Connect the Lamp House output aperture to the user equipment. The light output is
`coupled via a standard optical 1” threaded barrel. The beam should always be either
`directly coupled to a fiber optic cable, or enclosed in an appropriate beam pipe, tube,
`or enclosed space and purged with nitrogen. Operating the source without any output
`target or beam transport is not recommended, and may lead to unsafe operating
`conditions. Consult Energetiq
`for applications
`information and
`suggested
`configurations.
`3. Set up the Lamp House with appropriate ultraviolet safety measures and laser light
`safety measures in place. It is recommended that any enclosure or aperture-blocking
`hardware utilize cover switches wired to the EQ-1500 external interlock circuit.
`4. Place the Controller unit no farther than 6 feet from the lamp unit, as the supplied
`cable is only 2 meters long. Do not block the air vents at the front or rear of the
`Controller.
`5. Connect the supplied Signal/Power Cable to the Lamp House and the Controller.
`The connectors are polarized to prevent errors in setup. Be sure to screw the attached
`flathead connector mounting screws fully with 12 in-lbs torque.
`6. Connect cooling water and nitrogen purge gas to the Lamp House. Refer to “Facilities
`Requirements” above.
`7. Connect cooling water to the Controller unit.
`8. Verify that the main power switch on the back of the Controller is in the “OFF”
`position.

`Fiber installation procedure
`
`Step Picture
`8.1.
`
`Description
`Using the supplied 1/16” hex driver, remove the screws
`securing the lamp house cover. Carefully lift the cover
`straight up.
`
`8.2.
`
`8.3
`
`CAUTION: The shielded fiber located on the back of
`the controller has a minimum bend radius of 30mm. Use
`care not to bend the fiber too tightly.
`
`Cut the zip-tie securing the fiber to the back of the
`controller and then unwrap the fiber.
`
`
`
`Remove the SMA cap located inside the lamp house.

`
`While supporting the end of the fiber, place the strain
`relief against the side of the lamp house. You will see
`two ‘fingers’ that lock the strain relief in place from the
`back side. These will need to slide over the inside surface
`of the panel.
`
`Rotate the strain relief around the corner while keeping
`the locking ‘fingers’ on the inside.
`
`Move the strain relief all the way to the left. You should
`not be able to pull the strain relief straight out.
`
`Carefully remove the cap from the end of the fiber. Use
`care not to touch the end of the fiber. THE FIBER
`END MUST BE KEPT VERY CLEAN.- VERY
`IMPORTANT – See section on “Fiber Cleaning” at
`the end of this section.

`
`
`
`Again, use extreme care not to touch the end of the
`fiber. Carefully slide the fiber into the SMA connector
`and tighten finger tight.
`
`Using care not to pinch any wires, slide the lamp house
`cover back into place and install the cover screws.
`
`The fiber installation is now complete.
`
`
`9. Connect the supplied IEC cord from the Controller to the power source.
`10. Purge the EQ-1500 unit for at least 10 minutes prior to operation. Failure to purge
`the system properly may damage the optics and may produce ozone gas.
`11. Verify that cooling water is flowing and the temperature is at maximum 18 degrees C.
`Operation of the EQ-1500 lamp at a higher temperature will result in reduced
`performance and possibly shorter lamp life.
`Note: cooling water should be turned off when the lamp is not operating, to
`avoid condensation on internal and external cooling lines.
`
`
`The system is now ready to operate.

`
`
`
`
`Fiber Cleaning Process
`Fiber Cleaning Basics:
`• The LDLS laser fibers contain very high power densities, and are susceptible to
`damage if the LDLS is operated when the fiber connector is not clean.
`• Leave Laser Fiber SMA connected whenever possible
`• Minimize the number of fiber connections
`•
`If the SMA fiber must be disconnected, always use a cap on both ends:
`– Store caps open side down when possible
`– Blow out caps with CDA (Clean Dry Air) prior to use
`• Never leave the fiber disconnected without a cap
`• Follow the fiber inspection and cleaning process before making an laser fiber SMA
`connection
`• Operating the LDLS with a contaminated fiber introduces the risk of decreased
`performance or damage to the unit
`• Always remove AC power from the EQ-1500 before performing a fiber inspection or
`cleaning.
`
`
`
`Fiber Inspection and Cleaning Process:
`Note - Fiber Inspection should only be performed with power removed from the EQ-1500
`Power Supply Controller Unit
