Midinfrared “W” quantum-well diode lasers with reduced turn-on voltages are reported. Devices with coated facets operated in continuous-wave mode up to 195 K, where the emission wavelength was 3.56 μm. At 78 K, the threshold current density was 67 A/cm[sup 2], the maximum output power was 198 mW, and the slope efficiency was 106 mW/A. © 2003 American Institute of Physics.
