Abstract
A laser device including a wavelength converter of internal resonator type comprises a laser diode 20 for excitation, a light emission section 22 as a solid laser medium excited by the laser 20 and a wavelength converter 23 for converting the wavelength of the laser light from the excited solid laser. The solid laser medium of the light emission section 22 comprises a semiconductor crystal of GaAs, AlGaAs or GaAs-AlGaAs. A second harmonic wave light of a fundamental wave of 0.8 .mu.m band can be easily generated by using a solid laser medium such as a GaAs crystal, an AlGaAs crystal or a superlattice crystal thereof.
