Gain dynamics of XeF and subpicosecond pulse generation at 351 nm

Abstract

Subpicosecond pulse amplification at the 351 nm line of XeF is reported. The study of the gain dynamics of XeF with subpicosecond (subnanosecond) pulses resulted in 0.2 mJ/cm2 (0.8 mJ/cm2) for the saturation energy density and 0.18 cm−1 (0.21 cm−1) for the small-signal-gain coefficient. In XeF a gain recovery of 78±4% with a 79±18 ps time constant is found.
