In order to improve the output power and the reliability of the diode lasers with the quasi-continuous-wave(QCW) average power of ×102 W,the doubled-side cooling is used in conductively cooled packaging.The results show that after the use of the doubled-side cooling,the maximum output power and the slope efficiency of the diode laser are improved from 91.6 W,1.09 W/A to 98.4 W,1.16 W/A,respectively,and the threshold current is decreased from 15.6 A to 15.1 A.The wall-plug efficiency is increased...
