Title: Laser oscillation device
Inventor: MIYAZAKI TOSHIAKI
IPC: H01S3/134
Filed: 1987-06-05
Abstract: PURPOSE:To prevent laser beams from scarring and to facilitate the control, by disposing a Brewster's plate and P and S polarized beam-receiving means on a reflection side of a beam splitter and performing feedback control of output intensity of laser beams in accordance with P and S polarized beam intensity signals. CONSTITUTION:Laser beams A outputted from a laser oscillation means 12 are made to branch into transmitted laser beams B and reflected laser beams C by means of a beam splitter 16, and next the reflected laser beams C are made to branch into a P polarized laser beam component and an S polarized laser beam component by a Brewster's plate 17. A relation of P and S polarized laser beam components D, E, which are made to branch by the Brewster's plate, to the laser beams A is formed to be approximately linear because fluctuation of the laser beams can be neglected on the polarized beam surface. A P polarized beam-receiving means 18 and an S polarized beam-receiving means 19 are used to receive the respective beams so that a P polarized beam intensity signal S13p and an S polarized beam intensity signal S13s are detected and that the feedback control of output intensity of the laser beams A is performed in accordance with these signals. Hence the feedback control can be performed exactly and besides the laser beams can be prevented from scarring. Further the control can be facilitated.
