Abstract

PURPOSE:To obtain a highly efficient laser light with modulated frequency and strength by providing a semiconductor in a laser resonator and by supplying the semiconductor laser passage region with carriers. CONSTITUTION:A semiconductor 9 through which a laser light 5 passes is provided in a laser resonator comprising a laser activating media 1 and a pair of reflectors 2, 3. The semiconductor 9 comprises a laser light passage region 6 and a carrier generator region 8. In this construction, carriers are generated in the region 8 when a modulated voltage Vp applied between an electrode 10 provided in the semiconductor 9 and an electrode 22 provided in the semiconductor region 20, constituting the region 8, with the electrode 10 positive. If a direct current voltage Vd is applied between the electrodes 10 and 11 with the electrode 10 positive, the carriers travel through the region 6 and reach the electrode 10. While the carriers are in the region 6, refractive index becomes larger and the laser light 28 with modulated frequency and strength is obtained.
