Abstract
-
Experiment on the reflection of polarized monochromatic laser light at the planar interface of resonantly absorbing medium and the air, to measure its reflection properties and the state of polarization after reflection, were made for a variety of situations, including Brewster's angle in the spectral vicinity of the resonance wavelength. An ethanolic solution of Rhodamine B, an organic laser dye luminofor with a well defined resonance absorption spectrum, was chosen as the absorbing medium. The tunable polarized polarized output of a cw dye laser is used to provide the collimated monochromatic beam. To compare the experimental results with theory, the Fresnel reflectivity equations combined with the Kramers-Kronig relations were used to drive expressions to predict the state of polarization of the reflected beam in terms of the known absorption coefficient. The experimental results generally confirm the theoretical predictions.
