Laser Intracavity Modulation and Stabilization.

Abstract

The description of a method of generating optical-frequency sensitivity signals in single mode lasers is presented in this report. The technique involves controlled coupling of energy from the optical mode having gain to other laser cavity resonances using an intracavity phase modulator. The theory which applies to this work was obtained from the coupled mode equations of Harris and McDuff and is based on single mode laser stabilization theory of McDuff and Curtis. Experiments were performed which verified the theory using a single mode, carbon dioxide laser and a cadmium telluride (CdTe) electro-optic modulator. A closed loop system was constructed which was similar to that used by Targ, Osterink and French with a multimode, HELIUM-NEON laser. (Author)
