Nonlinear optical limiter of pulsed laser radiation based on potassium-aluminum-borate glass with copper chloride nanocrystals

摘要

This paper discusses the nonlinear optical properties of copper-containing potassium-aluminum-borate glass when it is acted on by a pulsed laser with wavelength 532 nm and pulse width 5 ns. It is shown that the nonlinear optical limiting threshold of the original copper-containing glass is 3 x 10(-3) J, while that of glass with copper chloride nanocrystals is 5 x 10(-6) J. It is shown that the maximum attenuation of a transmitted laser pulse with energy 0.05 J is a factor of 100 for the original glass with transmission 85, while it is a factor of 1000 for glass with copper chloride nanocrystals and transmittance 70. It is concluded that potassium-aluminum-borate glasses with copper chloride nanocrystals can be used as filter-limiters for the protection of the organs of vision and photodetectors from pulsed laser radiation.
