Abstract
A solid laser medium is pumped by a semiconductor laser in order to produce a solid laser beam. The solid laser beam having thereby been obtained is caused to impinge upon a crystal of a nonlinear optical material, and the wavelength of the solid laser beam is thereby converted into a different wavelength. A nonlinear optical coefficient of the crystal of the nonlinear optical material utilized for the wavelength conversion is represented by d.sub.IJ, where I, J=1, 2, 3, and an principal axis of indicatrix of the nonlinear optical material corresponding to J is represented by .alpha.. The direction of linear polarization of a laser beam, which is produced by the semiconductor laser and serves as a pumping beam, is set in the direction, which coincides with the principal axis of indicatrix .alpha. when it is viewed from the direction of incidence of the pumping beam.
