MULTIPLE PULSE EMISSION FROM A HCN LASER

Abstract

The time dependence of the output of a high‐energy HCN laser has been studied with an indium antimonide detector. At a CH₃CN partial pressure of 0.24 torr, three separate infrared pulses are emitted during a 250 μsec time interval after the current pulse. The addition of He, A, O₂ or H₂ changes both the number and delay between the pulses. As many as six pulses approximately 90 μsec apart in a 450 μsec period are observed with a He–CH₃CN gas mixture.
