A 20-J flow-compatible XeCl laser

The laser head and fast pulser for a high-energy, flow-compatible, X-ray preionized XeCl laser have been fabricated and tested. The pulsed power used to drive the 12*9*120 cm discharge utilizes a novel high-efficiency spiker sustainer circuit with a magnetic isolation switch. A single-pulse output energy of 19 J at 2.2% efficiency and a pulse length of 230 ns has been demonstrated, corresponding to an extracted energy density of 1.5 J/L.<
