= Self-pulsation
{wiki=Self-pulsation}
Self-pulsation refers to a phenomenon in various physical systems where an oscillation or fluctuation occurs spontaneously, without the need for external periodic driving forces. This behavior can be observed in several contexts, including: 1. **Optics and Lasers**: In certain laser systems, self-pulsation can occur when the gain medium's properties and the feedback from the cavity lead to oscillations in the output intensity of the laser beam.
