Abstract :
When a stripe-geometry heterostructure GaAlAs laser is irradiated by its own output beam, oscillations in the 1¿100 MHz range are generated in the laser, and the frequency f of the oscillation varies with the length 2L of the optical path of the beam returned as f = ¿(c/2L), with ¿ ¿ 1, where c is the velocity of light.
