The interaction between lasers and dielectric surfaces assisted by an isotropic source of energy

Our method of polarization of light incident at the Brewster angle on a dielectric surface allows finding indices of refraction with a precision of 0.0001 [1]. This precision allows us to generate accurate dispersive curves in visible and near visible range using relative inexpensive equipment. We propose a simple method for finding the dispersive curve for non-magnetic dielectrics using relative inexpensive diode lasers and an isotropic energy source. The idea is based on the scalar addition of energy from various sources on a dielectric surface. Our interpretation is inspired from the classical dipole oscillator model [2]. We use this technique to eventually create a strong coupling between two laser fields assisted by an isotropic source of energy, which simultaneously interact with the same dipoles of the dielectric. This experiment could be used as a simple experimental prove of the destructive interaction between a strong coupling laser and a weak probe laser with the creation of electromagnetic induced transparency in optical materials.\\[4pt] [1] Bahrim C and Hsu W-T, 2009 Am.
