High-quality InGaAs/AlGaAs laser diode bars emitting at 940 nm have been fabricated by low-pressure metal-organic chemical vapor deposition (LP-MOCVD). Two hundred and ten Watts maximum continuous-wave output power and a maximum power conversion e ciency of 60% at an output power of 72 W have been d
