摘要:

应用多光子非线性Compton散射模型,研究了固体温度变化对光声信号强度的影响。结果表明,在Compton散射光和入射光形成的耦合光强度和频率不变时,随固体温度的升高,光声信号强度非线性迅速增强;固体温度不变时,随耦合激光强度和频率的增大,光声信号强度几乎趋于0。

Abstract:

Using the model of the multi-photon nonlinear Compton scattering,the influence of laser energy and photo-acoustic signal intensity is studied by the change of solid temperature. The result shows that when the intensity and frequency of the coupling optical formed by between Compton scattering and incident optical beams have not changed,the photo-acoustic signal intensity will be quickly and nonlinearly increased along with the ascending of the solid temperature. When the solid temperature has not changed,the photo-acoustic signal intensity will nearly be zero along with the increasing of the coupling laser intensity and frequency.

Key words: Nonlinear optics, Photo-acoustic signal, Coupling, Multi-photon nonlinear Compton scattering
