Compact, Economical, High Brightness,
Broadband Laser-Driven Light Source

The compact LDLS EQ-99X is an ultra-high brightness, high
stability broadband source that is specifically designed for
demanding imaging and spectroscopy applications. The EQ-99X
offers excellent spatial and power stability for highly repeatable
measurements across the broad spectrum. Utilizing a patented
laser-driven bulb technology* the EQ-99X is ideal for applications requiring
ultra-long lamp life. The EQ-99X is available with a range of free-space broadband
reflective coupling optics to match the ~100µm plasma size to the customers instrument or application. With its high brightness, small plasma, the EQ-99X is particularly well suited to applications using narrow spectrometer slits, small diameter optical fibers or other small étendue optics.

The Technology Behind LDLS™

Researchers using light for imaging and analytical spectroscopy in a variety of applications in the life sciences and materials sciences need light sources capable of providing extremely high brightness across a broad wavelength range. Traditionally, multiple lamps (Tungsten/Halogen, Xenon-arc, Deuterium) have been used to cover this broad spectral range. However, combining multiple lamps is costly and optically inefficient, and the use of electrodes within these lamps limits their ability to achieve the high brightness or power needed for the most demanding applications. Furthermore, traditional electrode-driven light sources have short life, need to be changed frequently, and during their life the lamp output declines constantly. To address this problem, Energetiq has developed a revolutionary single-light source technology called the LDLS™ Laser-Driven Light Source that enables extreme high brightness over a broad spectral range, from 170nm through visible and beyond, combined with lifetimes an order of magnitude longer than traditional lamps.

Energetiq's innovative LDLS technology uses a CW laser to directly heat a Xenon plasma to the high temperatures necessary for efficient deep ultraviolet production. In traditional approaches such as arc and deuterium lamps, the brightness, UV power, and lamp lifetime are limited by the use of electrodes to couple power to the plasma. The electrodeless LDLS technology creates small, high brightness plasma that allows efficient light collection, broad spectral range from the deepest UV through visible and beyond, and long lamp life.
