EFFICIENT FREQUENCY DOUBLING OF A SELF-STARTING ADDITIVE-PULSE MODE-LOCKED DIODE PUMPED ND-YAG LASER

[摘要] Using a 1 W laser diode pump, a Nd:YAG laser has been passively mode locked using a coupled nonlinear external cavity to give a stable train of 2.0 ps pulses at an average power of 110 mW. This output has been frequency doubled with an overall energy conversion efficiency of 56%, using MgO:LiNbO3 in an external resonant enhancement cavity, yielding 63 mW of time-averaged power in bandwidth-limited 2.0 ps pulses at 532 nm.
