Abstract : The patent describes an ultra-fast terminator for intense laser pulses. A laser beam is brought to a focus between the electrodes of a low-inductance, laser-triggered spark gap, and then recollimated by a second lens as it diverges from the gap. When the intensity at the focus exceeds a preset level, laser-induced gas breakdown occurs, and the spark gap is triggered. The remainder of the laser pulse is absorbed in the dense plasma produced by firing the spark gap and the laser-induced breakdown itself, thereby terminating the laser pulse.
