Information circulation in a two-mode solid-state laser with optical feedback - art. no. 056239

A two-mode solid-state laser subjected to a delayed optical feedback is stu died. Simultaneous random switchings between stable and chaotic antiphase s piking oscillations featuring the establishment of causal (drive response) relationships among modes have been demonstrated by a proposed information circulation analysis of an experimental time series. The observed phenomeno n has been well reproduced by numerical simulations of two-mode laser equat ions with uncorrelated modal phase fluctuations.
