Broadband Antireflection-Coated Calcium Fluoride Cylindrical Lens for Multi-Wavelength Laser Beam Shaping

This dataset focuses on the design, preparation, and system level performance evaluation of wide band anti reflective coatings for large-diameter calcium fluoride (CaF ₂) cylindrical lenses, covering a complete experimental chain including film system design, optical characterization, surface morphology, thermo mechanical simulation, and beam transmission analysis. Specifically, it includes: film system design, material optical constants, theoretical and measured transmission spectra, weak absorption and temperature rise test data, surface roughness data, surface shape accuracy detection results, and wavefront detection data of the assembled system.

Simultaneously including finite element simulation results: simulation data of temperature rise and surface deformation at different absorption levels, as well as simulation data of 400 m long-distance beam transmission. This dataset can provide basic data support for the optical component design, low loss film development, and thermal effect evaluation of high-power multi wavelength laser beam shaping systems.
