Cavity-detuning characteristics of CW additive-pulse mode-locked Nd:YLF laser

Temporal and spectral characteristics of the pulses from the self-starting, additive-pulse mode-locked Nd:YLF laser using a nonlinear coupled-cavity are presented. Pulses of tunable widths are obtained over the coarse cavity-detuning range of 1 mm. Temporal shapes measured with a cross-correlation technique show that the pulses are asymmetric when the two cavity lengths are coarsely mismatched. The additive-pulse mode-locking characteristics under the fine cavity-detuning within the range of a wavelength are also investigated.<
