Abstract
We measured small-signal gain in a cw diode-pumped Cr:LiSAF and showed that upconversion and thermal quenching of fluorescence strongly limi t small-signal gain. Then we optimized the gain in a Cr:LiSAF laser pu mped by two 400-mW red diodes. In Q-switched operation, this laser pro duced tunable nanosecond pulses between 800 and 900 nm. At 850 nm, we obtained 230-ns pulses with an energy of 6.5 mu J at a repetition rate of 10 kHz. (C) 1996 Optical Society of America
