ABSTRACT:
In a laser diode pumped solid state laser, a primary solid state laser medium containing a rare earth metal is pumped by a semiconductor laser, and the wavelength of a laser beam having been obtained from the solid state laser oscillation is converted by a nonlinear optical material into a different wavelength. A solid state laser medium for injection locking is located between the primary solid state laser medium and the semiconductor laser. The solid state laser medium for injection locking is pumped by the semiconductor laser and produces a laser beam for injection locking through solid state laser oscillation in a single longitudinal mode, such that the laser beam for injection locking may impinge upon the primary solid state laser medium.
