Abstract

Abstract: We report on the efficient generation of the collinear and degenerate polariton pair via biexciton‐resonant hyper‐parametric scattering (RHPS) in a CuCl single crystal using the non‐collinear and two‐color excitation method. By using this excitation method, a strong emission peak is observed at one‐half of the biexciton energy ( E bx /2). The strong emission obtained at E bx /2 originates from the collinear and degenerate scattered polariton pair generated through the RHPS process. Furthermore, it is found that the energies of the scattered polaritons are split and deviated from E bx /2, when the energies of the two excitation pulses are changed. We discuss the variation of the scattered polariton energies with changing the energies of the two excitation pulses on the basis of the phase matching condition for the RHPS process.
