Description

The heat sink COOL50 was designed for temperature stabilization of high power laser diodes, laser arrays and laser stacks of about 50W optical power. Depending from the temperature difference between laser diode and ambient air the max. heat load is up to 120W. A heat sink includes the metal block, fans for the heat dissipation, the peltier elements (TEC´s), a heat spread plate with a temperature sensor, the laser diode cable and the cooler cable. For using laser diodes with integrated peltier elements and temperature sensor the heat sink is available without peltier elements, temperature sensor and heat spread plate for a reduced price.
