The influence of the absolute phase of a short light pulse on the third harmonic generation in an optically thin nonlinear layer

摘要

The third harmonic generation dynamics and the response spectrum of an optically thin layer of a medium possessing cubic nonlinearity depend on the absolute phase of a short light pulse with a small (-2%) detuning of the carrier frequency from that of the linear oscillator in the medium. The results of computer simulation show that a relatively small change in the absolute phase can result in a two-fold increase in the amplitude of the response pulse generated at the triple frequency.
