Stimulated parametric fluorescence induced by picosecond pump pulses

Abstract
Stimulated parametric fluorescence emission tunable over the range from 0.96 to 1.16 μ has been obtained using a barium sodium niobate crystal pumped by a frequency‐doubled and mode‐locked Nd3+:glass laser. The pump radiation in the form of a train of picosecond pulses produced infrared parametric fluorescence pulses, less than 10 psec in duration and with average peak powers on the order of 300 W when pumped with a power density of 300 MW/cm2.
