Toward single-shot characterization of nonlinear optical refraction, absorption, and scattering of turbid media
Abstract
Disordered media are often susceptible to optical damage even at low irradiation doses, since the correspond-ing microscopic structure may suffer from processes such as bleaching, chemical reactions, or morphologicalchanges. The disorder often introduces linear and nonlinear (NL) light scattering, and currently it is a challengeto perform single-shot characterization of NL refraction, NL absorption, and NL scattering using the morecommon NL transmittance techniques. This work discusses how the scattered light imaging method and D4σ techniques can be combined to characterize the NL optical constants of thick turbid media. Therefore, it shouldhelp researchers aiming to draw a detailed physical picture of turbid samples at the single laser shot level.
