To provide a small-sized and low-priced two-wavelength laser apparatus capable of obtaining two-wavelength laser light from one solid crystal at the same time. <??>In the laser apparatus including: a solid crystal of laser medium (2); a semiconductor laser diode (6) for excitation for generating laser light by exciting the laser medium and a condenser (5); and a reflecting mirror (1) and a laser output mirror (4) for resonating light generated from the laser medium, there is used a single crystal (2) PbWO4, which is a Raman crystal, as a solid crystal of laser medium to thereby perform laser emission of two wave length with one solid crystal at the same time. <IMAGE> |
