A surface initiated plasma temporal attenuator enabling production of CO2 laser pulses with tunable durations (20–90 ns), similar temporal profiles, and near Gaussian spatial profiles, is described. Use of the technique to investigate the pulse length dependence and thereby elucidate the mechanism of CO2 laser damage is demonstrated for uncoated and diamondlike carbon antireflection coated n-type Ge.

    Pulse duration as long as 14 μs has been obtained from a single longitudinal mode TEA CO[sub 2] laser. Such stretching occurred under conditions for which oscillation on a higher order transverse mode followed that on the TEM[sub 00] mode with partial temporal overlap between the two. Control...

    The UCLA Neptune Laboratory CO2 laser system has been recently upgraded to produce 3ps multi-terawatt 10μm laser pulses. The laser energy is distributed over several 3 ps pulses separated by 18 ps. These temporally structured pulses are applied for laser driven ion acceleration in an H2 gas...
