Description

DLW-series is a family of high power fiber-coupled water cooled diode lasers. Each laser consists of a fiber-coupled diode module, current source (laser diode driver), cooling system (Peltier modules, temperature controller, heatsink), user interface and coverage case. Cooling is performed with an external chiller.

We use only high quality fiber-coupled diode modules from the world-best manufacturers. Standard models are built up on nLight's modules. Modules by other manufacturers like Dilas, LIMO, JenOptics can be used instead on customer's request.

Laser's input is 110/230VAC mains, laser's output is a fiber, which distal end can be equipped with beam shaping optics of customer's choice. Interfaces are 7'' touch panel GUI and RS-485 machine interface.
