Abstract
Two convex lenses (), each of which has a focal length 'f', and a 90 degree polarization rotator () are interposed between solid-state laser elements () of a symmetrical resonator having the two solid-state laser elements (); a space between the two lenses () is made shorter than 2f; and distances between the respective lenses () and centers of their adjacent solid-state laser elements () are set substantially to 'f', to thus achieve a solid-state laser capable of stably performing high power transverse single mode oscillation desirably having power of 100 W or more. There is acquired a wavelength conversion laser that is further provided with a Q switch () and a polarization element () and that causes an output fundamental wave laser beam to enter nonlinear elements () so as to undergo wavelength conversion, thereby producing a high power harmonic laser beam having a high frequency of; desirably, about 100 kHz.
