Abstract

Presented in the work are the results of the development of a new combined CW ring single-frequency laser with universal design that allows efficient use as the active medium of both a Ti:Sapphire crystal and a dye jet. For the first time such combination has been implemented in a horizontal resonator configuration that offers an improvement of stability in the position of optical elements and more convenient operation. The short-term line width without the frequency stabilisation is less than 5 MHz (Ti:Sapphire) and < 10 MHz (Dye); with the frequency stabilisation to a specially designed thermo-stabilised reference interferometer with high finesse, the line width is less than 10 kHz (Ti:Sapphire) and 90 kHz (Dye), output frequency drift being less than 25 MHz/hour. The total working spectral range of the combined laser stretches from 550 to 1000 nm (550-770 nm for the Dye and 695-1000 nm for Ti:Sapphire) when pumped with 532/515-nm radiation. The maximum output power with a 10-W pump exceeds 2 W for the Ti:Sapphire configuration and is > 1 .5 W for the Dye one.
