Abstract
An intracavity wavelength conversion laser apparatus has a stable resonator in which a solid-state laser active medium, a resonator Q-value modulating element, and a wavelength conversion crystal, a nonlinear element, are arranged along a laser optical axis for generating a Q pulse wavelength conversion laser beam. A mirror constituting the stable resonator, which is positioned close to the wavelength conversion crystal, is a convex mirror, whereby the Q pulse wavelength conversion laser beam has a short pulse width. The laser apparatus is easily operated with high efficiency and has a small size. The Q pulse wavelength conversion laser beam is generated with excellent reproducibility and stability, and the wavelength conversion crystal is less susceptible to optical damage.
