Abstract

We describe an intracavity LiNbO3 Fabry-Perot etalon for frequency stabilization and tuning of a single-mode quasi-continuous-wave Ti:Al2O3 ring laser. Taking into account the 150μs pulse duration and the 40-Hz repetition rate of our laser, we achieve stabilization by 266-kHz modulation of 100-V peak-to-peak voltage applied to the electro-optic crystal. Tuning is ensured by the presence of a gain loop that contains a lock-in amplifier reacting with a multimorphous ceramic by means of 0–300-V dc voltage, which causes slight rotation of the LiNbO3 Fabry–Perot etalon. A continuous frequency scan of 6  GHz was made that potentially can be extended to 6 cm-1.
