Strong polarization effects in photothermal common-path interferometry

We show experimentally and theoretically that heating of highly transparent materials by continuous-wave pump beams induces strong optical anisotropy for probe beams in primarily optically isotropic configurations. This is due to a uniaxial thermally induced strain and the elasto-optic effect. The c...
