Abstract
A wavelength conversion laser device includes a laser light source for emitting a first wavelength light, a nonlinear optical crystal for converting the first wavelength light into a second wavelength light, and a nonlinear optical crystal rotator for rotating the nonlinear optical crystal so as to change an incident angle of the first wavelength light into the nonlinear optical crystal. The device also includes a nonlinear optical crystal rotation driving controller for controlling a rotation amount of the rotator in accordance with an output change of the second wavelength light so that the nonlinear optical crystal has phase matching with the first wavelength light. The device further includes a light exit position adjustor for compensating an exit position change of the second wavelength light in accordance with the incident angle change of the first wavelength light so that the second wavelength light is outputted in a predetermined exit position.
