[vc_separator][vc_empty_space height=”20px”]

High Brightness, Broadband with Fiber-Coupled Output

The Laser-Driven Tunable Light Source (LDTLS™)
is a compact, fully integrated and highly stable tunable
broadband light source that is based on our proven Laser-Driven
Light Source (LDLS™) technology. The LDTLS™ utilizes our EQ-77 LDLS™ broadband source and features the highest brightness and output flux available in a tunable broadband light source.

The LDTLS™ offers an extremely long lifetime of ~9000 hours between bulb changes for low cost of ownership. It has high stability, very low noise and is coupled with a precision high-performance monochromator for accurate wavelength selection and repeatable light output across the range of

 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.

ldls principle of operation Energetiq
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.
