Abstract

Resonant interactions of a coherent field with an anharmonic oscillator are classified based on the established analogy with multiphoton interactions of light with atoms. It is shown that interference interactions in which the absorption of a single coherent field quantum induces a multiphoton transition in the anharmonic oscillator are superpositions of resonances of the “cascade” and “lambda-V” types, and a general description of these resonances is given. For the third- and fourth-order nonlinearities, the general expressions are applicable to a resonant process with the absorption of a single photon and the double excitation of the oscillator. Resonant processes of the second harmonic generation and “rectification” of radiation are predicted and described; experimental investigation of these processes will provide information about anharmonicity parameters in the proposed model.

非谐振荡器中的干涉光子共振和非线性现象
相干场与非谐振子的共振相互作用是根据光与原子的多光子相互作用的类比进行分类的。研究表明,单个相干场量子的吸收在非谐振荡器中引起多光子转换的干涉相互作用是 "级联 "和 "λ-V "类型共振的叠加,并给出了这些共振的一般描述。对于三阶和四阶非线性,一般表达式适用于单光子吸收和振荡器双重激发的共振过程。对二次谐波产生和辐射 "整流 "的谐振过程进行了预测和描述;对这些过程的实验研究将为拟议模型中的非谐波参数提供信息。
