Description
Summary:Reactive Q switching of a CO2 laser by means of a piezoelectrically actuated end reflector is reported. The high‐frequency response of the piezoelectric transducer was maintained by optically polishing the transducer’s surface directly instead of employing a separate mirror. Submicrosecond pulses at rates in excess of 100 kHz were obtained. This technique is especially appropriate for generating high pulse rates in low‐power lasers, as no lossy intracavity elements are required.
