New Coolers for Laser Diodes Released

Recently Rogers Corporation’s Power Electronics Solutions (PES) group has released its new curamik CoolPerformance Plus coolers.

Roger’s said that “curamik CoolPerformance Plus is an advanced liquid-cooled material designed to dissipate large amounts of heat and provide reliable thermal management of high-power laser diodes and other heat-generating optical devices.”

These new coolers feature “aluminum-nitride (AlN) isolation layers to proven curamik CoolPerformance copper cooling structures,”  “ceramic AlN layers [to] separate the cooling water channels from the electrical contacts of laser diodes,” and  “they also provide a close match in coefficient of thermal expansion (CTE), in the range of 5 to 7 ppm/K, between the copper cooling structures and high-power ceramic laser diode packages for improved reliability even at high power levels,” according to the company.

The cooler’s mounting surfaces can be “diamond-milled to meet the fine tolerances required for mounting of laser diode packages, for optimum flow of heat away from the diodes.”

Rogers adds that “curamik CoolPerformance and CoolPerformance Plus coolers are well suited for applications in industrial, medical, and research applications, for thermal management of high-power laser diodes and diode-pumped lasers.”
