Abstract

A narrow-line laser has been developed for testing of narrow band optical filters. The frequency doubled Ti:sapphire laser, pumped at 20 Hz by a frequency doubled Nd:YAG laser, is tunable between 450 - 470 nm and line-narrowed to 6 mÅ with dichroic mirrors, a four plate birefringent filter, and a high finesse etalon. Although the laser was designed with sufficient selectivity to discriminate against adjacent axial modes, spatial hole burning in the standing wave resonator allows two axial modes to oscillate.
