Abstract

Self starting additive pulse mode-locking was first achieved in Ti:Al2O3 and was a significant development in the production of ultra short pulses. The technique utilises the phase dependent reflectivity from a resonant coupled cavity being intensity dependent due to the nonlinear element present. An initial intensity perturbation resulting from mode beating in the main laser is, in the presence of sufficient nonlinear feedback, progressively shortened and preferentially amplified on successive round trips, and grows to saturate the gain, resulting in steady state mode-locking. By removing the need for active made-locking, with its associated synchronisation problems, ultra short pulse durations were readily achieved, combined with a general simplification of the overall system. The wide applicability of the scheme has been demonstrated by its extension to other solid state gain media such as Nd:YAG, Nd:YLF and Nd:Glass.
