Abstract

The reliability of uncoated InGaAsP/GaAs high-power diode lasers emitting at 808 nm wavelength has been studied. 47 W of quasicontinuous wave output power (pulse width 200 μs, frequency 20 Hz) have been obtained from a 1-cm-wide laser bar. A single-stripe diode without mirror coating has been life tested at 40°C for emitting power of 800 mW continuous wave (cw) and showed no noticeable degradation and no change of the lasing wavelength after 6000 h of operation.
