Abstract:

Various techniques of optical frequency translation were investigated, leading to the design of a Y-shaped laser configuration that can simultaneously support independent oscillations having two separate polarizations. The device consists of two laser cavities sharing a single neodymium doped glass laser rod and end mirror. Theoretical and experimental studies of mode selection techniques and FabryPerot interferometric analyzers are presented. The work leads to single-mode operation for each separate frequency and effective methods of measuring translation. Tuning a single leg of the Y laser, translation over a total range of 18 Gc was achieved. Observation of simultaneous operation of both legs was also made. It was concluded that the method selected was feasible and that further effort is warranted. Author
