Abstract

A passive feedback control in an actively mode-locked pulsed Nd:YAG laser was used to shorten the pulse duration or obtain millisecond trains of ultra-short light pulses. The intracavity second harmonic generation in a crystal situated at proper distance from the output mirror served as a positive or negative feedback. When negative feedback was used, the length of the train was limited by the length of the flash lamp pumping pulse.
