Abstract :
>700 W continuous-wave output power has been demonstrated from a single 1 cm-wide laser bar (~940 nm) with 77% fill factor. Maximum power conversion efficiency (PCE) of 65% has been achieved. Facet power density of 170 mW/mum and maximum PCE of 69% have been measured for 10% fill-factor bars with 3 mm cavity length
