DILAS launches 500W 976nm fiber-coupled, multi-bar module

High-power diode laser maker DILAS of Mainz, Germany has launched a fiber-coupled, multi-bar module that can deliver up to 500W of output from a 400 micron fiber at a wavelength of 976nm.

The fiber-coupled, multi-bar modules deliver 500W through a cladding-mode-free quaternary buried heterostructures (QBH) high-power 400 micron core diameter fiber with a low numerical aperture of <0.2 and a wall-plug efficiency (WPE) of >35%. Packaged in up to 12-bar configurations, the designs are based on industry-standard conductively cooled bars, which are optically stacked and polarization coupled. The laser requires only industrial water for cooling.

While achieving high brightness and efficiency, the new module has demonstrated a lifetime greater than 10,000 hours under 500W continuous wave (CW) operating condition.

The fiber-coupled, multi-bar modules are suited to direct-diode applications as well as fiber-laser and solid-state laser pumping. Custom wavelengths are available upon request.
