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.
