Small signal gain investigations for a continuous-wave diode-pumped Q:switch Cr:LiSAF laser
Résumé
We measured small-signal gain in a cw diode-pumped Cr:LiSAF and showed that upconversion and thermal quenching of f luorescence strongly limit small-signal gain. Then we optimized the gain in a Cr:LiSAF laser pumped by two 400-mW red diodes. In Q-switched operation, this laser produced tunable nanosecond pulses between 800 and 900 nm. At 850 nm, we obtained 230-ns pulses with an energy of 6.5 mJ at a repetition rate of 10 kHz
