Abstract
The article examines the thermal model of a laser diode with a heat source of finite thickness and presents the calculation of thermoelastic stress waves arising at the time of the current pulse. It is shown that the decay of the thermoelastic tensile wave in the active region does not exceed 1 nsec; beyond the limits of the active region a compressive wave originates, and the time of its passage is equal to the time of passage of the wave through the active region. The amplitude of the wave attains 4.1·104 Pa with a plane heat source, and 1750 Pa when the active region is 10−7 m thick.
