Abstract

DFWM of picosecond pulses in some saturable absorbers used for modelocking Nd-doped laser material is reported. The performances of Kodok 9740, Kodak 9860, pentame-thylidyne dye and two new dyes HIE 1301, and HIR 1302 are compared by the intensity and time-resolution properties of signal waves, and the output characteristics of the laser by using these dyes in an active-passive mode-looked Nd3+:YAG laser are reported. The relaxation time of HIR 1301 and HIR 1302 are presented for the first time.
