摘要

This paper explores the use of the Fiber Laser Scribed Technique (FLST) for economically applying protective coatings to PZT energy meters. The suggested PZT energy meter focuses on protecting against excessive reflectivity, which could cause the energy meter to become overheated and damaged. The pulse power output from various lasers with samples of the same size with a diameter of 20 mm. PZT crystal samples made of lead zirconate have been extensively studied in order to gain information and comprehension of pulsed laser energy. The study seeks to develop a laser pulse energy meter that is cost-effective by enhancing the optical properties through protective coatings. The FLST employs Nd (1064 nm), second harmonic generation green (532 nm), and diode (802 nm) lasers to apply protective coatings on PZT energy meters. The optimal FLST parameters, with a speed/frequency ratio of 40/40 mm, achieved an absorbance of 94.48% and reflectivity reduction to 1.5%. A speed/frequency ratio of 80/40 mm using the 802 nm diode laser demonstrated a protective coating efficiency of 95.2%. Increased speed/frequency ratios in FLST resulted in higher reflectivity and lower absorption, which are suboptimal for PZT energy meter production. FLST is precise, durable and cheaper to manufacture and what makes it even better is that the material can be replaced quickly in case of any damage during exposure to lasers. As compared to the regular energy meters which would need to be maintained in case of damages, this design is fast and safe. As observed and analyzed in this study, the non-contact method of FLST is an effective protective strategy for PZT energy meters.
