Abstract

The characteristics of laser operation near threshold in a cw Nd:YAG laser are investigated. In the threshold region the laser operates in the form of pulses. The off states of the laser are intermittently interrupted by chaotic laser burst of the on states. Through an analysis of scaling in laminar phases, we verify that this phenomenon is the same on–off intermittency that was studied in nonlinear dynamics [Phys. Rev. E 49, 1140 (1994)].
