摘要：

A　semiconductor　disk　laser　with　a　transparent　chemical　vapor　deposited　diamond　heatspreader　is　presented.　The　gain　region　of　the　semiconductor　disk　includes　16　noncompensated　compressively　strained　InGaAs　quantum　wells.　710mW　continuous-wave　output　power　at　1043nm　is　produced　using　a　3%　output　coupler　and　6100mW　incident　pump　power.　The　slope-efficiency　is　14.2%　and　the　optical-to-optical　conversion　efficiency　is　11.6%.　The　effect　of　the　diamond　heatspreader　on　the　laser　is　also　analyzed.　©　2009　IEEE.
