Dilas announces the newest fiber-coupled, multi-bar module capable of delivering up to 1-kilowatt output from a 400-micron fiber at 976nm. Dilas’ fiber-coupled, multi-bar modules lead the industry in brightness and power featuring a compact footprint and convenient aiming beam. These fiber-coupled, multi-bar modules deliver 1-kilowatt through a cladding-mode free QBH high-power 400µm core diameter fiber with a low numerical aperture of <0.2 and WPE of >35%.  These bars are optically stacked by DILAS’ propriety beam stacking method and polarization coupled. State of the art macro-channel coolers are used in order to keep water requirements simple.

A 2-kilowatt version will follow with two wavelengths (i.e. 915nm and 976nm). All modules are available with either QBH (Optoskand) or LLK-B industrial fiber connectors. Fibers can be chosen between 400µm at NA 0.2 or 800µm at NA 0.12.

Custom wavelengths are available upon request. Line narrow versions, using VBG’s are available as well, providing 800W optical output power with spectral line width <1nm FWHM.  These fiber-coupled, multi-bar modules are ideal for direct diode application as well as, fiber and solid-state laser pumping.
