A New Technique for Measuring Laser Pulse Energy Using PZT/SiO2

This paper presents a novel laser pulse energy measurement method based on photoacoustic converters. The concept of paper design and built energy meters using PZT as three specimens have a diameter of (20, 24, and 25) mm, and coating SiO2 was chosen in this test because it has special properties, is affordable, and is compact in size. Genetic energy meters are expensive. Comparing the genetic meter (used in this study that is manufactured of pyroelectric material and PZT/SiO2). The outcomes demonstrated that within the laser pulse's energy (100-400mJ). Peak voltage values for PZT composites range from 0.48 to 0.84 volts at the voltage output as their diameter increases (PZT-S with a diameter of 20 mm). The output voltage ranges for PZT-M (diameter 24 mm) and PZT-B (diameter 25 mm) are 0.18 to 0.68 volts and 0.08 to 0.56 volts, respectively. The design has been built and characterized by measured voltage and energy meter sources. A piezoelectric actuator had been fabricated on silicon sand wafer composites by converting the light waves (the laser pulse) into shock waves. Unlike the energy meter type (pyroelectric) for genetic-, the energy meter created in (PZT/SiO2) is unaffected by Damage caused by high temperatures from laser Nd:YAG pulse energy
