Abstract

The effects of mirror instability and jitter (mechanical noise) in Q switched lasers is investigated. Pulse shapes and timing are significantly disturbed due to loss modulation induced by these effects. A simple model is presented. Several types of pulses are obtained, which are compared with experimental traces of a CO₂ rotating mirror Q switched laser. Loss modulation as a global means of pulse shaping is also discussed.
