Abstract
A short cavity dye laser (SCDL) as an efficient way to generate ultrashort pulses was first used by Roess.1 Recently, SCDL mixed with the saturable absorber DODCI pumped by pulsed laser had been studied theoretically and experimently.2,3 Here, it was found that under strong interactions within three bodies of laser field, DODCI and dye molecules, femtosecond pulse trains could be generated in the proper conditions.
