Four kinds of laser dyes were pumped by a repetitive pulsed mode-locked YAG laser. A dye laser has been obtained with the parameters as follows: pulse repetition rate of 20 Hz, peak power of the order of MW, average output power of the order of mW, spectral line-wodth of 0.05nm, tunable wavelength ranging from 550.0-689.0nm, pulse duration of 30 ps. The output characteristics of the two matching dye are compared experimentally.
