Abstract

A novel infrared broadband nonlinear optical limiting (NOL) technology based on stimulated Brillouin scattering (SBS) in

{As}_{2} {Se}_{3}

fiber is proposed. The

{As}_{2} {Se}_{3}

fiber allows a weak infrared laser to pass through, but blocks an intense laser with the same wavelength due to the SBS effect. This NOL technology has been experimentally proved to have excellent NOL performance for incident pulsed lasers with a typical infrared wavelength of 3.6 µm. The linear transmissions of 1 m and 0.5 m
