Abstract
Abstract The properties of short-pulse generation in KrF and XeCl lasers by fast mode locking using a square-wave-driven Pockels modulator are investigated numerically. The influence of the most important parameters of the laser system on duration and peak power of a pulse generated is analysed in detail. A comparison of an active and active–passive case of mode locking is also carried out. It is shown that the method considered can be an efficient way for picosecond pulse production in rare-gas halide excimer lasers enabling considerably shorter (∼ 10–20 times) and more powerful pulses than those attainable with conventional mode locking techniques used so far to be obtained.
