摘要：

Separate　heat　source　profile　basing　on　structure　of　semiconductor　laser　array　is　applied　in　thermal　resistance　calculation　of　microchannel　heatsink　as　boundary　condition.　Relationships　between　emitter　width,　position　and　thermal　resistance　are　presented　and　optimized　length　of　microchannel　at　different　semiconductor　laser　arrays＇　cavity　length　are　also　gotten　through　numerical　calculation　.Semiconductor　laser　array,　with　1mm　cavity　length,　100　μm　emitter　width　and　25%　fill-factors　is　packaged　on　the　presented　microchannel　heatsink　and　tested.　With　an　exterior　size　of　27　mm11　mm1.5　mm,　thermal　resistance　of　microchannel　heatsink　reaches　0.34　K/W　and　matches　the　need　of　high　power　semiconductor　laser　array＇s　cooling.
