On off Intermittency in Diode Pumped Intracavity Frequency Doubled Nd: YAG Laser

We have investigated characteristic outputs of laser diode pumped intracavity frequency doubled Nd!YAG laser when small periodic gain modulations are applied. In the threshold region, the off-states of the laser operation are intermittently interrupted by the chaotic laser pulsations of on-states. From an analysis of scalings of laminar phases, we verify that the experimental results are the very on-off intermittency.
