摘要

Abstract: Stimulated Raman scattering of picosecond pulses was investigated in KGd(WO$-4$/)$-2$/, and BaWO$-4$/ tungstate crystals. BaWO$-4$/ crystal was previously found to be a new very efficient material for pumping with nanosecond pulses. In our experiment, we used the second harmonic output of a mode-locked Nd:YAG laser system, which generated single pulses of 28 ps duration. The length of the crystal was 40 mm for KGW, 23 mm for KYW and 29 mm for BaWO$-4$/. The SRS threshold, conversion efficiency, and time dependence of the first Stokes with picosecond resolution were measured. Picosecond Raman gains at a 532 nm wavelength were found to be correspondingly 11.5, 18.7, and 14.4 cm/GW for KGW, KYW, and BaWO$-4$/. The Raman shifting up to the third Stokes component was detected, and the first Stokes conversion efficiency reached 30 percent in BaWO$-4$/ and 18 percent in KGd(WO$-4$/)$-2$/. Measurements of a temporal pulse length have shown that the first Stokes pulse was twice shorter than the pump pulse. The new BaWO$-4$/ crystal occurs to be an efficient solid state Raman material for a wide variety of pump pulse durations. !19
