MAINZ, Germany, Feb. 14, 2012 — Dilas is continuing its expansion of wavelengths for its high-power diode laser bars by extending its offerings to water-cooled laser diodes for alkali laser pumping at 766, 780 and 852 nm on microchannel heat sinks at continuous-wave power levels of 40, 60 and 100 W, respectively.

The laser bar geometry is based on the industry standard of 1-cm bar width, with 19 emitters on a 500-µm 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.

Suitable for research and development, defense and other diode-pumped alkali laser applications, the diodes are assembled in water-cooled stacks to power scale 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.
