Single-mode tunable UV source based on laser diode injected intracavity doubled Ti:sapphire laser

Summary form only given. There is an increasing need in ultraviolet tunable coherent sources for different applications such as atmospheric studies. It has been recently shown that pulsed intracavity doubling of vibronic lasers could be a good alternative to existing dyes if their low yield and multimode operation problems could be alleviated. Indeed, in the pulsed regime, only a small portion of the broad oscillating continuum is phase-matched to the nonlinear crystal. For what we believe to be the first time, we show that injecting an intracavity doubled Ti:sapphire laser allows both problems to be solved, i.e., to obtain a high yield (/spl ap/50%) and a single-mode operation.
