Title: Intracavity wavelength conversion solid-state laser generator

Abstract: Fundamental laser light having a wavelength of 1,064 nm, for example, is generated by a solid-state laser medium. The fundamental laser light is reflected by a flat mirror and amplified again passing through a Q-switch, a solid-state laser medium, a Q-switch, a Q-switch, a solid-state laser medium, and a Q-switch. The fundamental laser light furthermore reflects from a flat mirror, passes through a flat mirror for second-harmonic resonance, passes through a lens, then reflects from a flat mirror for laser light separation, and enters a nonlinear optical crystal for the third harmonic and a nonlinear optical crystal for the second harmonic. A solid-state laser generator can thereby be obtained in which second-harmonic laser light obtained in an intermediate stage can be used with good efficiency and be converted, for example, to third-harmonic laser light and higher-harmonic laser light with higher efficiency and higher output.
