The short-pulse lasers enables the generation of high peak power pulses in a short time, which are useful for the investigation of non-linear effects and for the investigation of time dependent effects. With q-switching in so called active or passive mode, it is possible to generate such short pulses.
Beside the generation of short pulses, the behavior of the Nd:YAG laser can also be the subject of additional investigations, like measuring the threshold, slope efficiency and so on. By using the optional Pockels cell (AQ) including the high voltage driver (QD), active q-switch can be performed and explored.
