Light Quantization with Classical Fields in Strong Laser

Abstract

In this paper is demonstrated that quantum ef-fects can be derived in a straightforward manner from the classical radiation intensity equation. To accomplish this, it is employed the equation done by Hartemann and Kerman inside the framework of Nonlinear Compton backscattering. Thus, through mathematical procedures involving the usage of integer-order Bessel functions, it is derived expressions that are in fully agreement to the quantum mechanics formulation of coherence as the one given by Glauber by which a Gaussian profile is representing the coherent states of light. The resulting classical field of emission is interpreted from the spectrum consisting of classical radiated energy against Doppler frequency. It has yielded peaks that are been interpreted ad emitted photons.
