Abstract
An experimental investigation was made of subpicosecond KrF pulse (400 fs) amplification in a low-pressure (<400 Torr) Kr/F 2 laser medium pumped by a short-pulse electron beam (20 ns fwhm, 860 keV, 19 kA) in a longitudinal lambda-geometry configuration with a pulsed axial magnetic field of 2.7 kG. The net small-signal gain was observed to be 1%/cm at a total pressure of 200 Torr (Kr/F 2=99.5/0.5 (%)) and an electron current density of 39 A/cm 2. Because of the low small-signal gain length product the amplified spontaneous emission (ASE) fluence in this mode was confirmed to be extremely small (less than μJ/cm 2) compared to the normal pressure mode (> 1 atm) operation.
