Subpicosecond pulse generation in a synchronously mode-locked cw rhodamine 6G dye laser.

We report the generation of wavelength-tunable subpicosecond pulses in a synchronously mode-locked rhodamine 6G dye laser, pumped directly by a mode-locked argon-ion laser (pulsewidth approximately 100 psec). The nearly transform-limited subpicosecond pulses are tunable in the 5625-to 6045-A spectral range. Peak powers of approximately 1 kW have been obtained.
