Abstract
- Type-II “W” diode lasers with ten quantum-well periods operated in pulsed mode to 315 K, where the emission wavelength was 4.02 μm. The devices with uncoated facets had a threshold current density of 145 A/cm2 and slope efficiency of 47 mW/A per facet at 78 K, and displayed a characteristic temperature T0≈46 K in the range 78–300 K.
