Tunable and compact femtosecond Cr:LiSAF lasers: single prism and prismless approaches

50 nm and 30 nm of smooth, continuous tuning is demonstrated in a compact Cr:LiSAF laser using single-prism and prismless approaches respectively. Pulses of /spl sim/150 fs in duration are generated for electrical drive powers of < 1.2 W.
