An electrically tunable semiconductor laser system is given using an acousto-optic (AO) device and a commercially available semiconductor laser. Rapid scanning of laser oscillation frequency is obtained using frequency modulation of the driving RF power for the AO device. Also, simultaneous two-frequency oscillation is realised using two RF power sources.
