| Abstract: | We report the observation of sustained self-pulsing behavior of the output of a channel waveguide Nd:YAG laser under a CW pump. The duration and repetition rate of the pulses observed were dependent on the pumping power. At the maximum pumping power available (44 mW of absorbed power), the pulse duration was around ～40 ns, and the pulse repetition rate was ～1.4 MHz. We discuss the possible physical mechanisms that generate the pulsing behavior, and their implications on the observed pump-power dependence of the repetition rate. |
