Abstract
An e-beam-pumped KrF laser has been developed as a middle-stage amplifier of a 1-kJ system for laser fusion research. The laser shown in Fig. 1 consists of one Marx generator (1 MV, 11 kj), two PFLs (4.6 0, 100 ns) with laser triggered output switches, two e-beam diodes (10 X 60 cm2), and a laser cell (20- X 20- X 60-cm3 active volume). Two e-beams are injected into the cell through carbon-sprayed Kapton anode and pressure foils. Up to now, a 120-J (70-ns) laser pulse has been generated with a 90% output coupling flat-flat resonator at 80 % voltage operation. Overall efficiency is 1.5% in this case.
