OFI vacuum ultraviolet rare-gas excimer amplifier for subpicosecond VUV pulse amplification

We evaluated amplification characteristics of the nanosecond vacuum ultraviolet argon excimer emission at 126 nm, whose kinetics was initiated by high-intensity femtosecond laser-produced electrons. Subpicosecond 126 nm emissions were produced simultaneously as a result of the nonlinear wavelength conversion, which will be amplified in the amplifier.
