The characteristics of laser operation near threshold in a ew 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 chao
tic 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 th
at was studied in nonlinear dynamics [Phys. Rev. E 49, 1140 (1994)]. (C) 20
