A stable passive Q switch for a neodymium laser

The processes of formation of ultrashort laser pulses

“…However, the stage of emission non-linear interaction with the dye is accomplished at the low intensity of USP oscillator (~ 10 MW cm -2 [17] for dye N3955 solution in nitrobenzene). The USP containing the main part of the train energy saturated the dye completely, and therefore there was no discrimination.…”
