抄録

The laser performance of BeZnCdSe single-quantum-well green laser diodes (LDs) was improved. In particular, high-power lasing over 50 mW was achieved. The high-resolution lasing spectrum indicates a peak wavelength of 536 nm. The far-field patterns (FFPs) of the 5-μm-wide mesa LDs show unimodal characteristics, and the perpendicular and horizontal beam-divergence angles for full width at half maximum are 21 and 2.2°, respectively. The wall-plug efficiency (WPE) of the 2-μm-wide mesa LDs is 3.6% at an optical output power of 50 mW. The internal loss (\alpha_{\text{i}}) and internal differential quantum efficiency (\eta_{\text{i}}) of the 10-μm-wide-mesa LDs were estimated to be 3.5 cm-1 and 0.22, respectively.
