<p>A laser light generating apparatus comprises a light source (1) for generating an exciting light beam, a condenser lens (2) for converging the exciting light beam from the light source (1), a laser medium (5) for generating a laser light of first wavelength by the radiation of the exciting light beam supplied thereto through the condenser lens (2), a nonlinear optical crystal element (6) for generating a second laser light by the radiation of the first laser light generated from the laser medium (5), a pair of reflecting means (7, 3) for constituting a laser resonator (9) together with at least the laser medium (5) and the nonlinear optical crystal element (6), a deflecting element (21) for deflecting an optical axis of the second laser light emitted from reflecting means (7) provided at the emitting side of the pair of reflecting means, detecting means (22) for detecting a part of a light beam output from reflecting means (7) disposed at the output side of the pair of reflecting means, control means (23 to 25) for controlling the light source (1) on the basis of a detected output from the detecting means (22) and a housing (11) for housing a base on which there are disposed at least the light source (1), the condenser lens (2), the laser medium (5) the nonlinear optical crystal element (6), the deflecting element (21) and the detecting means (22). <IMAGE></p> |
