Abstract

By frequency-tripling the output from an injection-seeded Ti:sapphire laser, we achieve in excess of 10 mJ of continuously tunable, narrow-linewidth ultraviolet laser light. The pulsed Ti:sapphire oscillator is pumped by a frequency-doubled Nd:YAG laser and is seeded with a cw Ti:sapphire laser to produce narrow-linewidth, continuously tunable infrared light. The seeding source, an actively stabilized cw Ti:sapphire laser, allows for continuous tuning in the infrared. For a 250-mJ pump pulse, the Ti:sapphire system achieves 75 mJ at 761 nm. The narrow-linewidth infrared output is tripled by a set of BBO crystals. Pumping the crystals with 75 mJ of injection-seeded infrared laser light achieves greater than 10 mJ of output at 253.7 nm.
