Stochasticity and coherent structures in ultra-long mode-locked lasers

Dmitry Churkin

Research output: Unpublished contribution to conferenceAbstractpeer-review


Ultra-long mode-locked lasers are known to be strongly influenced by nonlinear interactions in long cavities that results in noise-like stochastic pulses. Here, by using an advanced technique of real-time measurements of both temporal and spatial (over round-trips) intensity evolution, we reveal an existence of wide range of generation regimes. Different kinds of coherent structures including dark and grey solitons and rogue-like bright coherent structures are observed as well as interaction between them are revealed.

ConferenceSIAM conference on Nonlinear Waves and coherent structures
Abbreviated titleNW14
Country/TerritoryUnited Kingdom
OtherTheoretical aspects of applied mathematical research on nonlinear waves and coherent structures are relevant to subjects as diverse as general relativity, high-energy particle and plasma physics, fluid and solid mechanics, nonlinear electrical circuits, Bose-Einstein condensation, nonlinear optics, random media, atmosphere and ocean dynamics, chemical reactions, and biology. Remarkable agreement between theory and experiments can be claimed in many of these fields.

The goals of the conference are to provide a forum for the development of mathematical methods and tools, to foster cross-fertilization among different fields of application, and most crucially to enable communication between the mathematicians who build the theory and the scientists who use it. The conference program will consist of presentations on subjects ranging from basic mathematical research to concrete applications.
