Abstract

We report the first demonstration, to the best of our knowledge, of tunable and Q-switched lasers based on diode-pumped Nd,Lu:CaF2 disordered crystal. A continuous tuning range of approximately 32nm (1047-1079nm) was obtained for tunable operations. A passively Q-switched laser was successfully achieved using a Cr4+:YAG as a saturable absorber. The shortest pulse width of 275ns was obtained with a repetition rate of 1.85kHz and corresponding peak power and single pulse energy of 189W and 51.9μJ, respectively.
