Quasi-continuous-wave and actively mode-locked diode-pumped Cr(3+):LiSrAlF(6) laser

We have developed a 500-mW cw diode-pumped Cr(3+):LiSrAlF(6) laser that produces 72-mW, quasi-continuous-wave output at 850 nm. In actively mode-locked operation, we obtained 100-ps pulses at 860 nm with 30 mW of average power. Pulses with durations of less than 130 ps have been measured between 820 and 880 nm.
