非线性光学谐振腔中的双曲横向斑图

Hyperbolic Transverse Patterns in Nonlinear Optical Resonators

K. Staliunas, M. Tlidi

摘要:

我们考虑一个非线性光学系统,特别是一个宽口径激光器,在谐振腔中,衍射系数沿两个横向方向的符号相反。该系统由双曲Maxwell-Bloch方程描述,其中空间耦合由DAlambert算子而不是Laplace算子提供。我们发现,该系统支持双曲横向图案居住在双曲线在远场域,并在近场域拉伸涡组成。这些结构的解析描述的规范形式分析,并进行了数值研究。

英文摘要:

We consider a nonlinear optical system in general, and a broad aperture laser in particular in a resonator where the diffraction coefficients are of opposite signs along two transverse directions. The system is described by the hyperbolic Maxwell-Bloch equations, where the spatial coupling is provided by the DAlambert operator rather than by the Laplace operator. We show that this system supports hyperbolic transverse patterns residing on hyperbolas in far field domain, and consisting of stretched vortices in near field domain. These structures are described analytically by normal form analysis, and investigated numerically.
