2.5kW fiber-coupled diode laser system

Mainz, Germany -DILAS has debuted the SF2500/10 fiber-coupled diode laser system with output power of 2.5kW at 980nm for use in materials processing applications. The system is based on micro-channel cooled diode laser bars featuring a compact footprint and convenient aiming beam. With a beam parameter product of 110mm mrad, the system delivers 2.5kW through a cladding-mode-free QBH high-power 1000µm core diameter fiber with 0.22NA at single wavelength of 980nm.

The stand-alone, fiber-coupled diode laser system includes a water-water heat exchanger and diode laser driver inside a compact chassis. The company's DLC control unit provides standardized external interfaces.

Applications for the system include surface treatment (selective hardening), cladding, and high-power brazing, as well as scientific research applications that require large spot sizes and uniform intensity profile.
