摘要：

For　the　980　nm　high-power　laser　diodes　manufactured　by　Beijing　Opto-electronic　Technology　Lab,　the　relation　between　the　power　conversion　efficiency　of　the　best　operating　point　and　the　cavity　length　is　analyzed.　Experimental　results　show　that　the　best　output　power　increases　while　the　power　conversion　efficiency　decreases　with　the　cavity　length　increasing.　Analyses　indicate　that　the　defect　power　is　the　primary　factor　resulting　in　the　decrease　of　photoelectric　conversion　efficiency　and　reducing　the　inner　loss　is　most　obvious　way　to　improve　the　power　efficiency　of　the　best　operating　point.
