Abstract: An infrared source producing a coherent output having a spectrally narrow and continuously tunable frequency is described. Such a source uses a four wave mixing process in an alkali metal vapor, wherein the initial input beams to the alkali metal vapor come from two dye lasers. In an alternative mode of operation, tunable ultraviolet output is obtained.

Abstract: A capacitive discharge in cesium vapor is used to realize an externally controllable Q-switch synchronizing the appearance of pulse trains from a passively mode-locked neodymium glass laser with other events occurring on a microsecond time scale.
