Abstract

There is an increasing need in high peak power single mode ultraviolet tunable coherent sources for different applications such as atmospheric studies, Raman spectroscopy, biology,.. It has been recently shown that pulsed intracavity doubling of vibronic lasers could be a good alternative to existing dye systems These lasers however are plagued by their low yield (few percent) and their multimode operation. We show that laser diode injecting an Intra-Cavity Doubled Ti:Sapphire (ICDTiS) allows both problems to be solved ,i.e, to obtain a high yield (10 fold enhancement) and a single mode operation. Anti-phase matching behaviour is observed where minimum yield is obtained at phase matching maximum, and explained using a simple theoretical model
