MAINZ, Germany, Sept. 21, 2011 — Dilas now offers higher-power fiber-coupled multibar laser modules operating at 1940 nm. The high-brightness, high-power modules feature a compact footprint and deliver 30-W output through a 600-µm core diameter fiber with a low numerical aperture of 0.22 and wall-plug efficiency of >10%. The designs are based on industry-standard conductively cooled bars that are optically stacked and polarization-coupled. The modules require only industrial water for cooling. Custom wavelengths are available upon request. The fiber-coupled multibar modules are suitable for direct diode applications, such as welding of transparent plastics, medicine and defense.
