Phys. Rev. Lett. 93, 213904 (2004) [4 pages]Time-Resolved Dynamics of Two-Dimensional Transverse Patterns in Broad Area LasersReceived 5 April 2004; published 17 November 2004 We report the first direct experimental observation of the fast dynamics (nanosecond scale) of complex two-dimensional transverse patterns in broad area lasers. The laser emission bright peaks forming the transverse patterns are observed to be aperiodically flashing in time with different growing rates. These optical filaments do not move along the cross section during their lifetime, which is close to 2 ns. The experimental observations have also been reproduced by numerical integration of the Maxwell-Bloch equations. © 2004 The American Physical Society URL:
