Broadband anti-reflective composite coating: Effect of pulsed laser treatment on optical properties

The developed method of laser treatment for the formation of antireflective coatings on the basis of composite materials created by filling epoxy polymer with multi-walled carbon nanotubes has been demonstrated. The influence of surface structuring of composite materials by pulsed laser treatment on reflectivity in UV-, visible- and IR wavelength ranges (0.2–25 $\mu$m) has been investigated. A composite material was created and structures with low reflectance in the specified wavelength range were formed on it. Optical characteristics of such structures meet the standard requirements for anti-reflection coatings of optoelectronic and optical systems of aerospace vehicles.
