ABSTRACT:
The present invention is a wavelength conversion laser apparatus for converting wavelength by utilizing a nonlinear optical crystal and capable of safely using it over a long time. For this end, the fundamental wave laser light emitted from the pumping chamber unit3which is a solid state laser light source is converted into the second harmonic wave by the first nonlinear optical crystal unit20. And the second harmonic wave is, then, converted into the third (or fourth) harmonic wave by the second nonlinear optical crystal unit30. Filled in the container24, 35for each of the nonlinear optical crystal units20, 30is a dry inert gas. A humidity sensor51detects humidity inside the container. The output from the humidity sensor51is supplied to the laser control portion58. When the detected humidity exceeds a predetermined value, the laser oscillation is interrupted, thereby preventing the nonlinear optical crystal from being damaged in case of any defect in the sealing structure of the container.
