We report a compact and wavelength-tunable periodically poled lithium niobate (PPLN) Q-switched laser with intra-cavity optical parametric generation,producing 8-us,10-μJ pulses at 10-kHz repetition rate when pumped with a 10-W diode laser at 808nm.The output wavelength can be tuned from 1450nm to 1600nm.Multiple-pulse generation was observed in the experiment.
