摘要：
A simple method for the generation of short, single-mode CO2 laser pulses produced by applying two voltage gates (of amplitude 3U(lambda/4) and U(lambda/4)) to an electro-optic Q-switch placed in a three-mirror cavity is proposed. Single, single-mode, well-synchronizable pulses of 3 ns duration and of 3 mJ energy have been experimentally achieved from a TEA CO2 laser with an intracavity Pockels cell with 3 ns switching time. Using a numerical simulation it is shown that with shorter switching time (almost-equal-to 1 ns) the method enables one to obtain, from such a laser, a single, megawatt pulse of 1 ns duration.
