Abstract

In this paper, we present results on the generation of 10.9 fs duration pulses directly from a self mode-locked Ti:Sapphire laser. Ultrashort-pulse operation of the laser was obtained by optimizing the intracavity dispersion compensation. A short, highly-doped Ti:Sapphire crystal and fused silica prism pair were used to achieve this. We also present preliminary results on frequency doubling of the 800 nm fundamental beam, both inside and outside the laser cavity. Detailed calculations have been made on a number of nonlinear crystals to determine the optimum crystal choice. Our calculations indicate that intracavity doubling should lead to the generation of sub-20 duration ultraviolet pulses.
