Patent ID: 7254148

Claim:
A laser light generating device comprising an excitation light source for generating a continuous-wave excitation light and a solid-state laser resonator based on using thermal lens effect available at a position of excitation in a laser medium, characterized in that: said solid-state laser resonator is configured so that individual substrates having individual constituents of said solid-state laser resonator disposed thereon are integrated by bonding, and so that reflection means or a saturable absorber of said solid-state laser resonator is opposed to said laser medium while placing an intermediate medium in between; said constituent of said solid-state laser resonator has an interface inclined from a plane orthogonal to an optical axis of said excitation light, and a light path length of said solid-state resonator in a direction parallel to an optical axis of said excitation light differs depending on setting of said position of excitation; and characterized by having an output wavelength of 700 nm or longer, and 1,600 nm or shorter.
