Title: Methods for an alternating beam ring laser. Master's thesis

Technical Report ·
OSTI ID:6382890

The purpose of this research is to investigate the feasibility of three methods of alternating beams in ring lasers. The first method is the use of a Faraday cell and a half-wave plate inside the laser cavity to rotate the plane of polarization of one of the counter-rotating beams so that lasing in that direction is not supported. The second method, and the one investigated experimentally, is the use of mirrors and a mechanical chopper external to the laser cavity to halt lasing by means of mode competition. The third and final method explored is the replacement of the mechanical chopper with an electro-optical shutter.
