Abstract
A deep-ultraviolet violet laser beam which is a harmonic and is generated inside a nonlinear optical element ( ) is emitted outside the nonlinear optical element ( ), being spaced from a green laser beam, which is a fundamental wave. The green laser beam emitted outside the nonlinear optical element ( ) is reflected by an input-coupling mirror ( ) and applied again into the nonlinear optical element ( ) in order to form a closed optical path for the fundamental wave. Also, the deep-ultraviolet laser beam emitted outside the nonlinear optical element ( ) is reflected by a reflecting mirror ( ) other than the input-coupling mirror ( ) in order to emit the deep-ultraviolet laser beam from a deep-ultraviolet laser beam-generating section ( ).
