DILAS introduces high-power diode laser bars on micro-channel coolers

DILAS, Mainz, Germany, continues its expansion of wavelengths by extending its offerings to water-cooled laser diodes for alkali laser pumping at 766nm, 780nm and 852nm on micro-channel heat sinks at CW power levels of 40W, 60W, and 100W, respectively.

The laser bar geometry is based on the popular 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, as measured at 20C.

A good choice for research and development, defense and other diode-pumped alkali laser applications, these diodes are assembled in water-cooled stacks to power scale up to kW levels, according to user 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.
