ABSTRACT:
In a laser-diode-pumped solid state laser, a solid laser crystal is pumped by a pumping laser beam emitted from a laser diode and a harmonic of light emitted from the pumped solid laser crystal is caused to make laser oscillation by a resonator structure containing therein a nonlinear optical crystal. The electric current to be poured into the laser diode is controlled so that the pumping laser beam emitted from the laser diode is kept at an output level at which the pumping laser beam cannot cause the harmonic of light emitted from the solid laser crystal to make laser oscillation though pumping the solid laser crystal.
