Abstract
A length stabilized, dispersion compensated synchronously pumped mode locked dye laser is disclosed. The output of the dye laser is actively stabilized by monitoring the output power thereof and generating an error signal for actively adjusting the cavity length. The operation is enhanced by actively controlling the power of the pump pulses exciting the dye laser so that the power fluctuations in the dye laser are due primarily to fluctuations in cavity length. Stability is also enhanced by operating the cavity with a negative group velocity disperison. The resultant lengthening of the output pulses is compensated by a pulse compressor, located outside of the cavity, which adds a positive group velocity disperison to upchirp and shorten the pulses.
