DILAS launches high-power laser bars on micro-channel coolers for diode-pumped alkali laser pump wavelengths

High-power diode laser maker DILAS of Mainz, Germany has continued the expansion of its wavelength range by extending its portfolio to water-cooled laser diodes for alkali laser pumping at 766, 780 and 852nm, on micro-channel heat sinks at CW (continuous wave) power levels of 40, 60 and 100W, respectively.

The laser bar geometry is based on the popular industry standard of 1cm bar width, with 19 emitters on a 500┬Ám pitch with fill factor options of 20% and 30%. Typical power conversion efficiency is in the range of 56% at rated power for all three wavelengths, as measured at 20°C.

Suited to R&D, defense and other diode-pumped alkali laser applications, the diodes are assembled in water-cooled stacks to scale power up to kiloWatt levels, according to customer requirements.

Diode laser stack arrays can also be offered with volume Bragg gratings (with standard or low-reflectivity coatings) and with both optical axes collimated.
