摘要

在单泵单声子系统中，四向混合(4WM)和高阶斯托克斯(HOS)的产生的影响已经被研究过在本论文中，我们将发展一个提供多泵多声子系统运动方程的一般理论，该系统包括通过拉曼和4WM的所有对场相互作用。本文将分析和数值研究泵浦对和4WM的相干长度对HOS产生的影响。泵耗竭和反馈效应由于高阶过程将包括在内。在马尔可夫近似中，声子模式的消相将通过声子-声子相互作用得到

Four-wave-mixing Processes in Multiple-pump Multiphonon Systems: Effects of Coherence Length

The effects of four-way-mixing (4WM) and the generation of high-order Stokes (HOS) in a single pump single phonon system have been studied previously.1 In the present paper we shall develop a general theory which provides the equations of motion in a multiple pump multiphonon system which includes all pair field interactions via both Raman and 4WM. The effects of the coherence length of the pump pairs and of the 4WM on the generation of HOS will be investigated analytically and numerically. Pump depletion and the feedback effects due to the high-order processes will be included. The dephasing of the phonon modes will be derived via the phonon-phonon interaction in the Markovian approximation.2
