1940nm Fibre-coupled multi-bar modules

Dilas, the diode laser company, now offers higher-power fibre-coupled, multi-bar modules operating at 1940nm.

Dilas’ fibre-coupled, multi-bar modules feature a compact footprint. These modules deliver 30W through 600µm core diameter fibre with a low numerical aperture of NA 0.22 and WPE of >10 per cent. 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 modules are ideal for direct diode applications, such as welding of transparent plastics, medical or defence.
