`
`Light source lifetime lifted with laser tech
`
`2011 R&D 100 Winner
`
`The capabilities of spectroscopes and
`similar imaging solutions have been
`transformed in recent years by
`improvements in analytical
`instrumentation that operate in the
`ultraviolet, visible, and nearinfrared
`(UVVisNIR) wavelengths. These
`tools require a high brightness light
`source, typically provided by
`excimer, deuterium, xenon short arc,
`or mercury discharge lamps. Each
`have advantages and disadvantages;
`but markedly, all have less than
`1,000 hours of lifetime because they
`rely on corrosionprone electrodes that coat the bulb's surface with
`eroded material.
`
`Energetiq_EQ99 Power
`
`The EQ99 LDLS LaserDriven Light Source, produced by Energetiq
`Technology Inc., Woburn, Mass., provides the high brightness required
`by UVVisNIR instruments and has a lifetime in the 10,000 hour range.
`The enabling technology for this product is Energetiq's LaserDriven Light
`Source, a 20W continuouswave laser diode that directly heats a xenon
`plasma to high temperatures, providing a flat output spectrum from the
`NIR range down to 170 nm. Electrodes in the bulb ignite the plasma and
`then shut off. The laser alone sustains the plasma temperature, allowing
`gas temperature to climb in a comparatively small collection area with
`dimensions of about 100 ?m. This, along with higher plasma
`temperatures, boosts detection efficiency across the wavelength range.
