Two projects at the Los Alamos National Laboratory require lower jitter than available from standard commercial excimer lasers. The first experiment demanded an optical pulse width of only 5 ns. With the ± 5-ns jitter of the commercial lasers, it was impossible to achieve the desired timing accuracy. The second application uses commercial lasers as a diagnostic tool to determine the temporal profile in a large-aperture laser experiment. This arrangement uses three different lasers, all of which must be timed within a nanosecond in order to obtain accurate data. This report describes the standard laser performance before modifications, the modifications, and the resulting jitter reduction. In all four cases, jitter was reduced to less than 0.75-ns peak to peak. Details on the electrical and mechanical modifications are included.
