This is a project in the study of control of spatiotemporal complexity in nonlinear optical systems. Spatiotemporal irregularity and spontaneous pattern formation are intrinsic and universal phenomena in nonlinear optical systems that may seriously degrade the operation of the system in certain critical applications. The work will focus on studying spatiotemporal control in a unidirectional ring resonator that uses a refractive crystal to provide two-wave mixing gain and a laser that operates with many transverse modes. The experiments will be accompanied by theoretical calculations using a two-dimensional model for the resonator and a one-dimensional model for the laser.

这是一个研究非线性光学系统时空复杂性控制的项目。时空不规则性和自发图案形成是非线性光学系统固有的普遍现象，在某些关键应用中会严重影响系统的运行。这项工作将重点研究单向环形谐振器的时空控制，该谐振器使用折射率晶体提供两波混合增益，并使用多种横向模式操作的激光器。实验将伴随着理论计算，使用二维模型的谐振器和一维模型的激光。
