Efficient frequency doubling of a self-starting additive-pulse mode-locked diode pumped Nd:YAG laser

Efficient frequency doubling of a self-starting additive-pulse mode-locked diode pumped Nd:YAG laser
Using a 1W laser diode pump, Nd:YAG and Nd:YLF lasers have been passively mode-locked using a coupled nonlinear external cavitv, to give a stable train of pulses. Pulsewidths as short as 2.0ps have been achieved in Nd:YAG, and 1.4ps in Nd:YLF, with average powers of 110mW. The output of the Nd:YAG laser has been frequency doubled using MgO:LiNbO3 in an external resonant enhancement cavity. An overall energy conversion efficiency of 56% yielded 63mW of average power in bandwidth-limited 2.0 ps pulses at 532nm.

Abstract

Using a 1W laser diode pump, Nd:YAG and Nd:YLF lasers have been passively mode-locked using a coupled nonlinear external cavitv, to give a stable train of pulses. Pulsewidths as short as 2.0ps have been achieved in Nd:YAG, and 1.4ps in Nd:YLF, with average powers of 110mW. The output of the Nd:YAG laser has been frequency doubled using MgO:LiNbO3 in an external resonant enhancement cavity. An overall energy conversion efficiency of 56% yielded 63mW of average power in bandwidth-limited 2.0 ps pulses at 532nm.
