Abstract

Since its discovery coupled-cavity modelocking has become an increasingly popular method of mode-locking, its use extending from colour-centre lasers to other types of laser. Theoretical prediction^[1] showed that this phenomena was not due to a solitonic effect, as initially thought. Since then this type of modelocking has been examined experimentally in much more detail^[2] leading to the discovery of new features and a better characterisation of the mode-locking. Despite the early work and the additive pulse mode-locking theory (APM)^[3] there have been only a few attempts to model the coupled-cavity system and to try and observe the features seen experimentally, probably due to the problem being potentially computationally intensive. The work reported here details the latest findings of a numerical model^[4] that is showing features seen experimentally and is now revealing a better insight into the synergy of the coupled cavities.
