ABSTRACT
Determines the thermal stationary nonlinear refraction with enhanced sensitivity by measuring the profile distortions of a probe light beam in the presence of absorption of a collinearly propagating pump light beam. Accomplishment of a signal similar to the well-known Z-scan signal; Deduction of a simple formula related to induced thermal phase shift.

    Optical microscopy and manipulation methods rely on the ability to focus light to a small volume. However, in inhomogeneous media such as biological tissue, light is scattered out of the focusing beam. Disordered scattering is thought to fundamentally limit the resolution and penetration depth...
