An investigation was made of the threshold, power, and spectral characteristics of radiation emitted by GaAs--AlAs heterostructure injection lasers with double confinement and short (up to 16 ..mu..) plane-parallel resonators. The lasers had mesastripe contacts 10--14 ..mu.. wide. The gain coefficient was a linear function of the pump current density in the gain coefficient range 10--400 cm/sup -1/. The minimum threshold currents in the lasers were 27--30 mA and single-frequency lasing regime was observed right up to pump currents of (1.6--1.7)I/sub th/. The maximum single-frequency output power was 35 mW. It should be possible to retain single-frequency regime in such lasers when the pump current was subjected to high-frequency modulation.
