摘要
Two InGaP/AlGaInP red laser diodes are studied at pressures up to 16 kbar and at temperatures down to 80 K. Emission wavelengths below 570 nm have been obtained, with low thresholds and high efficiencies. Pressure dependence of threshold currents is very different for the two lasers indicating that electron leakage occurs predominantly to L minima in one laser and to X minima in another laser.
