Parametric generation of tunable picosecond light pulses as a result of pumping with radiation from a stimulated Raman scattering compressor

Typical parametric oscillations were observed in a laser with a stimulated Raman scattering compressor. This laser generated pulses of ~ 15 ps duration at a wavelength of 0.63 μm and the width of the spectrum was ~ 0.7 cm^{– 1}. The parametric radiation was tunable within the range 1–1.5 μm. A study was made of the statistical properties of the generation process. The energy stability of the pulses generated in such an optical parametric oscillator was twice as high as in the case when pumping was provided by a picosecond YAG:Nd laser with passive mode locking.
