Design of energy meter for laser pulse energies Nd: YAG (1.06 µm) and SHG (532 nm) using PZT/SiO2 composites.

The PZT crystal is a crucial technological element in the field of energy systems. This study created a pulsed laser energy meter using a lead zirconate titanate crystal (PZT) based on the piezoelectric effect. It operates in the visible and near-infrared range. A pulsed Nd: YAG laser was used to evaluate several crystals of various (20,24) mm in diameter. Due to the scale's increased surface area, the scale responds to tiny energies less when the sample diameter is bigger. The results appeared that piezoelectric sensors' response to mechanical impacts as a function of the voltage signal at PZT/SiO2 small diameter at values (0.9 Volt) to measure high energy using Nd: YAG (1.06µm). The sensor was manufactured under the best conditions possible is used a pulse laser of a wavelength of 1064 nm and a second harmonic-generated laser source (532 nm). In order to enable identification, storage, and calibration, The main focus of the findings is how mechanical impacts influence piezoelectric components as a function of the voltage signal sent by the Arduino-connected software during execution. Unlike the energy meter type (pyroelectric)type (Genetec QE-500)., Damage brought on by Nd: YAG laser pulses' high temperatures have no effect on the (PZT/SiO2) energy meter. The produced energy meter made materials more straightforward, affordable, and extremely effective. [ABSTRACT FROM AUTHOR]
