Femtosecond pulses at 800 nm by passive mode locking of Rhodamine 700.
We report the passive mode locking of a Rhodamine 700 dye laser in the near infrared. Using a short cavity in order to avoid multiple pulses and by adjusting the intracavity dispersion, we have produced 50-fsec pulses at 800 nm with HITCI as the saturable absorber.
