Paper Abstract

Novel efficient and compact package of high power laser diode arrays with single piece microchannel heatsink cooling was designed. The width of microchannel was optimized by theoretic analysis. Using single piece microchannel heatsink we manufactured 5 bars high power laser diode stack and obtained 40W CW output, the lifetime of laser diode stack was more than 5000 hours.
