Abstract :
A high-power pulsed water vapor laser beam passing through humid air produces a large amount of sonic energy easily detected by the ear. Using an ultrasonic transducer as a detector the effect has been observed on eleven emission lines between 17.55 microns and 78.41 microns. This detection scheme is very useful for laser alignment and beam tracing.
