High-power distributed Bragg reflector lasers operating at 1065nm

A report is presented on distributed Bragg reflector lasers emitting in excess of 700 mW in a single-spatial and single-spectral mode at 1065 nm. The threshold current of these devices is ~30 mA, there is an L-I slope of 0.74 W/A, and a sidemode suppression ratio greater than 30 dB. The current and thermal tuning are 0.016 A/mA and 0.7 A/degC, respectively.
