Diode laser company Dilas now offers higher-power fibre-coupled, multi-bar modules operating at 1940nm delivering 30W through 600µm core diameter fibre with a low numerical aperture of NA 0.22. These designs are based on industry standard conductively-cooled bars, which are optically stacked and polarisation coupled. The product requires only industrial water for cooling. Custom wavelengths are available upon request. These fibre-coupled, multi-bar modules are for direct diode applications, such as the welding of transparent plastics and medical and defense applications.
