Abstract

Coherent elastic waves were generated and detected at 114,000 megacycles per second in quartz at liquid-helium temperatures. Effective input power was approximately 3 milliwatts. The results suggest that the piezoelectric method may be applicable to similar experiments at much higher frequencies.
