Abstract
The distinguishing features of the watt-ampere characteristics of cw planar heterolasers and their dependence on the temperature and on the cavity length are investigated. It is shown that nonlinearity of the watt-ampere characteristic is accompanied by definite changes of the electric characteristics of heterolasers. Observation of the current-voltage characteristics permits diagnostics of laser operation without optical measurements. The question of incomplete voltage saturation on the laser p-n junction is considered and a phenomenological model of the effect is presented. Experimental data are given on the properties of lasers with linear, nonlinear, and hysteresis watt-ampere characteristics, as well as of lasers operating in the single-frequency regime.
