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