Femtosecond anti-Stokes free-induction decay and photon echo in a dye-doped polymer film, doped with dye molecules, and the possibility of coherent optical cooling

The anti-Stokes model, explaining of the experimental data of on study of the femtosecond photon echo in the dye-doped polymer film at room temperature, is developed. The possibility of realization of the anti-Stokes regime of coherent laser cooling in such films is analyzed.
