Optically pumped vecsels for high resolution spectroscopy: the new Ti : sapphire?

Research output: Chapter in Book/Report/Conference proceedingConference contribution book


We report the CW performance of two broadly tuneable, optically pumped VECSEL gain structures operating around 850 nm and 960 nm. We have achieved 0.75W at 852 nm in diffraction limited TEM00 mode. A tuning range in excess of 30 nm has been demonstrated with the use of an intra-cavity birefiringent filter. At 960 nm we have achieved a power of 1.75 W and a tuning range in excess of 35 nm. Stabilised single frequency operation with a line width stabilised to 85 kHz r.m.s. at the 0.5 W output power level is reported.
