Abstract
A new type of pulsation was observed in the output from a (GaAl)As double‐heterostructure injection laser which happened to have two lasing filaments closely located to each other. We observed repetitive pulsed lasing in one filament and corresponding dipping in the other. This pulsation was interpreted to be due to lateral optical coupling between the two filaments.Keywords
