Generation of subnanosecond light pulses in CdS

Subnanosecond light pulses (λ =495 nm, τ =6×10^-11 sec) were generated in CdS single crystals (T = 77 °K) by excitation with the third harmonic of radiation emitted from a mode-locked neodymium laser. The angular divergence, luminescence spectra, and stimulated emission spectra were determined at various pumping (by neodymium laser radiation) rates.
