Abstract
We report on the cavity-length detuning characteristics of a synchronously pumped femtosecond linear-resonator cw dye laser. The severe cavity-matching requirement (to within 0.2 μm) for optimum short-pulse generation is addressed by an active cavity-length stabilization scheme based on second-harmonic generation. This allows pulses ~100 fsec in duration to be maintained for periods of several hours.
