ABSTRACT:
A laser light beam generating apparatus includes at least one light beam source, resonator and an optical system. The resonator generates a type II second harmonic laser light beam. The resonator has a first reflector, a second reflector, a laser medium provided between the first and second reflectors and irradiated a light beam emitted from the light beam source through the first reflector and a non-linear optical crystal element provided between the laser medium and the second reflector. The optical system radiates the type II second harmonic laser light beam emitted from a virtual luminance point of the resonator to a conjugate point. In this laser light beam generating apparatus, with an effective length of the resonator L, an effective distance Le from the resonator to the conjugate point is set to that
