Paper Abstract

Presented is a new combined CW Ti:Sapphire/Dye laser with horizontal output polarisation from a ring cavity and with improved stability of output frequency. Short-term output line width does not exceed 10 kHz for the Ti:Sapphire laser and amounts to 50 kHz for the Dye laser, output frequency drift being less than 30 MHz/hour, smooth scanning range is more than 19 GHz (Ti:Sapphire) and > 25 GHz (Dye). The maximum output power with a 10-W pump exceeds 2 W for the Ti:Sapphire configuration and is > 1.6 W for the dye one. The short-term line width without the frequency stabilisation is less than 5 MHz (Ti:Sapphire) and < 10 MHz (Dye); smooth scanning range without the frequency stabilisation is more than 47 GHz (Ti:Sapphire) and > 50 GHz (Dye). 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.
