Abstract

We have investigated the transition route in a gain-modulated intracavity frequency-doubled Nd:YAG laser pumped by a laser diode when a small gain is modulated periodically. Through analysis of the probability distribution and the scaling relationship as the parameters of a laser system are varied, we ascertained that the intermittent laser operation of the intracavity second harmonics is an on–off intermittency. This is what we believe is the first observation of the transition route in a gain-modulated laser system. As further evidence of this transition route, similar intermittent behaviors were obtained in an acousto-optically Q-switched Nd:YAG laser pumped by a laser diode.
