Parametric superfluorescence in KTiOPO4 crystals pumped by 1 ps pulses

Abstract
Parametric superfluorescence in KTiOPO4 crystals pumped by 1 ps pulses is demonstrated using an amplified synchronous mode‐locked dye laser. The tuning range of the output pulses is from 0.93 to 1.59 μm. The maximum output power at the degenerate wavelength of 1.2 μm is 0.85 μJ, and a conversion efficiency of 9.9% is obtained. Height gain under phase mismatching broadens the spectral bandwidths of the output pulses.
