摘要

本文分析研究了顺磁晶体在次太赫兹范围内产生二次声谐波的脉冲状态。在无相群匹配和二次谐波频散参数为零的情况下，得到了相应的慢变振幅双色孤子非线性波动方程的精确解。在输入脉冲的载流子频率相对接近杂质顺磁离子的塞曼亚能级之间的量子跃迁谱线的地方形成了孤子。

Subterahertz Acoustic Solitons under Second-Harmonic Generation Conditions

The pulsed regime of second acoustic harmonic generation in the subterahertz range in a paramagnetic crystal has been analytically studied. An exact solution of the corresponding nonlinear wave equations for slowly varying amplitudes as a two-color soliton has been obtained in the absence of phase and group matching and at zero group velocity dispersion parameter at the second harmonic frequency. The soliton has been shown to be formed at a relative proximity of the carrier frequency of the input pulse to the spectral line of the quantum transition between the Zeeman sublevels of impurity paramagnetic ions.
