High-energy, high-efficiency harmonic generation from a Cr:LiSrAlF{sub 6} laser system

We have developed a near-diffraction-limited {ital Q}-switched Cr:LiSrAlF{sub 6} (Cr:LiSAF) laser system capable of producing 860-nm, 400-mJ pulses at a repetition rate of 2 Hz. Our harmonic-generation experiments with {beta}-BaB{sub 2}O{sub 4} nonlinear crystals have yielded 200 mJ of energy at 430 nm and 40 mJ at 215 nm. To the best of our knowledge, the 50% second-harmonic conversion efficiency and UV energy demonstrated in this research are the highest yet obtained from a Cr:LiSAF laser.
