Research abstract
Removing heat critically limits the application of high power laser diode stacked arrays to many high-value-added commercial markets where they would have commanding competitive advantages, including solid state and gas laser pumping; communications; laser welding; heat treating; alloying; high speed printing and various medical uses. XEMET's technology will remove on the order of 5 KW per square centimeter, with a temperature drop of 1 to 2 degrees C. per KW. XEMET's approach avoids the plumbing, pumping, sealing, clogging and the erosion problems of microchannel cooling. It removes 10 to 100 times the heat flux of diamond and avoids the CTE problems of diamond. Additional benefits are higher laser duty cycles, better reliability, longer life and improved optical performance.
