This dataset contains PMMA UV damage testing and characterization data from 2023 to 2025, aimed at investigating the UV performance of PMMA.
Listed in ScienceDB
This dataset documents a comprehensive experimental study on the ns-pulse ultraviolet (UV) laser-induced damage characteristics of Polymethyl Methacrylate (PMMA).
Description
It includes raw and processed data generated from controlled laser irradiation experiments and subsequent characterization performed between 2023 and 2025.Key data encompasses:Laser Irradiation Conditions: The damage tests were conducted using a 355 nm laser with a pulse width of 6 ns (FWHM).
The laser beam was focused by a 500 mm focal length lens to achieve a Gaussian spot with a 1/e² diameter of 157.5 μm. The maximum available pulse energy was 300 mJ.Characterization Data: Results include laser-induced damage threshold (LIDT) measurements, UV-Vis spectroscopy data (for transmittance/absorption changes), and optical microscopy images (for damage morphology analysis).Primary Objective: The dataset aims to investigate the fundamental damage mechanisms of PMMA under high-power UV ns-laser exposure.
