Field patterns in periodically modulated optical parametric amplifiers and oscillators
摘要：
本文研究了周期调制光参量放大器和振荡器中的空间局域场和周期场。在简并情况下（等信号光和闲频光），我们详细阐述了在放大器中构造定态局域模的系统方法，研究了它们的性质和稳定性。我们描述了一种构造光学参量振荡器周期解的方法，通过调整外部驱动场的形式，以给定的信号或泵浦光的形式。
英文摘要：
Spatially localized and periodic field patterns in periodically modulated optical parametric amplifiers and oscillators are studied. In the degenerate case (equal signal and idler beams) we elaborate the systematic method of construction of the stationary localized modes in the amplifiers, study their properties and stability. We describe a method of constructing periodic solutions in optical parametric oscillators, by adjusting the form of the external driven field to the given form of either signal or pump beams.
