Three rapidly tunable organic dye lasers have been developed and evaluated in an effort to produce a frequency agile laser with optimum beam properties. The basic design of each system comprises a pulsed nitrogen gas laser optical pump source, a 0.001 M rhodamine 6Gethanol active medium, and an optical resonant cavity with an intracavity tuning device that rapidly changes the wavelength of narrow-band stable oscillation. Their difference lies in the type of intracavity tuning device employed. One system is operated with a galvanometer-driver optical scanner, another with an optical scanner driven by piezoelectric bimorph strips, and the third with a rapid scanning Fabry-Perot interferometer.
