Nanosecond Calibration of a Piezo Transducer by Comparing Thermoacoustic and Vaporization Pressure Signals at Pulsed Laser Irradiation of a Metal Target

A possibility of calibrating a piezo transducer by comparing thermoacoustic and vaporization pressure signals generated in a metal (liquid mercury) irradiated with nanosecond laser pulses is demonstrated. In this calibration method, significant difference in the dependence of these two pressure gene...

Description
Summary:A possibility of calibrating a piezo transducer by comparing thermoacoustic and vaporization pressure signals generated in a metal (liquid mercury) irradiated with nanosecond laser pulses is demonstrated. In this calibration method, significant difference in the dependence of these two pressure generation mechanisms on the irradiated surface temperature is used.
