Abstract
We present an experimental investigation of an optical limiting device made of a colloidal suspension of spherical particles. It is based on nonlinear light scattering due to a photoinduced refractive index mismatch between the two components of the suspension that appears at high beam intensity. Several experiments performed at 532 nm with nanosecond laser pulses are described and the origin of the optical intensity limitation is discussed.
