Fibre-coupled, multi-bar diode laser module

Share this on social media:

Dilas, the diode laser company, has released a fibre-coupled, multi-bar diode laser module. This micro-channel-cooled unit is capable of delivering up to 6kW output at a wavelength mix of 9xxnm through a 1,000µm, 0.22NA fibre. It combines multi-kilowatt fibre-coupled diode laser power with a small footprint and high efficiency. The 19-inch rack-mountable unit is designed to meet the requirements for OEM customers and system integrators.

The laser module is designed as a beam source without an integrated power supply and also without a cooling unit, allowing system integrators a deep integration into their machine. The module is equipped with internal electronic sensory elements which monitor parameters like humidity, temperature operating current and other parameters, to ensure safe operation of the unit. In addition, the unit is equipped with a pilot beam for positioning purposes.

Applications include cladding, brazing, hardening and heat conduction welding. With its fibre interface based on QD fibre connector it can be combined with commercially available processing optics.
