Laser-Driven Light Sources (LDLS)

Laser-driven light sources (LDLS) use a high-power diode laser to energize a xenon plasma ball — generating ultrahigh-brightness broadband radiation across a spectral range of 170nm to 2,100nm from a single compact source. This approach replaces the multiple lamp types — deuterium, tungsten-halogen, and xenon arc — previously required to cover the deep ultraviolet through near-infrared range in a single analytical instrument.

LDLS technology uses high-power diode lasers to energize high-intensity xenon plasma, producing broadband radiation from 170nm to 1,700nm with ultrahigh brightness and long source life. The xenon plasma forms at a fixed point in space determined by laser focus geometry rather than electrode position — giving LDLS sources 5 to 10 times better spatial stability than conventional xenon arc lamps.

The Energetiq EQ-99X and EQ-77 LDLS models deliver much higher brightness across the full UV-Vis-NIR spectrum and an order of magnitude longer operational life than traditional lamp sources. Lamp lifetime on LDLS systems reaches 9,000 hours between replacements on the LDTLS tunable variant — significantly reducing the cost of ownership and maintenance interruptions in production analytical environments. The EQ-400 model delivers spectral power greater than 10mW/nm coupled into a 500µm aperture — making it suitable for applications requiring high power alongside high brightness, including satellite instrument calibration at NASA Goddard Space Flight Center.

These sources serve Pakistan’s university physics and chemistry research departments in Lahore and Karachi, pharmaceutical analytical quality control laboratories, semiconductor and thin-film research programs, hospital spectrophotometry instrument maintenance teams, and defense electronics optical sensor calibration programs at NESCOM and SUPARCO requiring stable, broadband UV-to-NIR illumination from a single long-life source.
