DLK Cooling Device for Diode Lasers

DLK Cooling Device for Diode Lasers

Diode lasers place special demands on the cooling unit. Therefore, we have developed a completely new performance class of laser cooling devices especially for the requirements of diode lasers – our series DLK. The cooling requirements are partly rather different from those of other lasers. Our series DLK offers our customers a wide variety of possibilities to match the cooling units exactly with the diode laser with respect to its performance data and the components to be used. Expensive diodes demand a reliable cooling. And that is why we think that only the best components are good enough for the manufacture of our laser coolers!
