LOCKING OF He–Ne LASER MODES INDUCED BY SYNCHRONOUS INTRACAVITY MODULATION

摘要: Bell Telephone Laboratories, Incorporated Murray Hill, New Jersey (Received 11 May 1964) placed at the Brewster-angle to mlOlmlze reflection losses and as near as possible to the end mirror. The standing acoustic wave in the block acts as a diffraction grating, producing diffraction orders which fluctuate in intensity at twice the driving frequency. All except the zeroth (central) diffraction orders go out of the cavity during tne first pass, as indicated by the dashed arrows in Fig. 1. For a stationary acoustic wave in the block, the normalized single …
