Abstract

In an earlier work,¹ it was shown by one of the authors that a large hysteretic cyclotron motion of a free electron can be excited by two laser beams with their frequencies much higher than a cyclotron frequency Ω_c and differing either by Ω_c (three-photon resonance) or 2Ω_c (four-photon resonance). Here we consider the feasibility of arbitrary order multiphoton excitation of free electron cyclotron resonance by a biharmonic laser radiaton with two frequencies ω₁ and ω₂ so that ω₁ – ω₂ ≃ nΩ_c, where n is an arbitrary integer.
