Combined cw single-frequency ring dye/Ti:sapphire laser

A new combined cw single-frequency dye/Ti:sapphire laser with a ring resonator located in the horizontal plane and improved radiation frequency stability is developed. The short-term radiation linewidth does not exceed 10 kHz for the Ti:sapphire laser and is smaller than 100 kHz for the dye laser. The drift velocity of the emission line does not exceed 25 MHz h^-1. The scheme and design of the developed laser are presented which allow convenient switching of the laser between its solid-state and dye configurations.
