THEORETICAL DESCRIPTION OF HARMONICS GENERATION FOR TWO-LEVEL ATOMS
二能级原子谐波产生过程的理论描述

The process of harmonic generation for a two-level atom is investigated theoretically.The model of oscillator driven by a nonlinear external force is used to simulate an induced porlarization of the atom,and the characteristics in harmonic spectrum of the atom are analyzed for a weak and a super-intense laser pulses.
