| 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. |
