摘要
A novel AIN monolithic microchannel cooled heatsink for high power laser diode array is introduced.The high power stack laser diode array with an AIN monolithic microchannel heatsink is fabricated and tested.The thermal impedance of a 10 stack laser diode array is 0 121℃/W.The pitch between two adjacent bars is 1 17mm.The power level of 611W is achieved under the 20% duty factor condition at an emission wavelength around 808nm.
