Abstract:

This paper presents the results of the development of modules for protecting the eyes from laser radiation in the visible and near-IR regions. A description is given of a nonlinear-optical module with a medium based on a suspension of carbon nanoparticles in a silicone liquid, a multispectral interference filter having narrow reflection bands with minimal transmission at wavelengths of 355, 532, and 1064 nm, and a system adequate for observational devices with embedded protective elements. The combined use of the protective modules makes it possible to reduce the energy at the output of the system to a level no greater than 200 pJ when the input energy is 50 mJ and the pulse-repetition rates are as much as 10 Hz, thus ensuring the safety of the observer’s eyes.
