Abstract
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; 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 PbWO.sub.4, 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.
