论文摘要
在这项工作中，我们提出了一种新颖且实用的方法，用于在高功率激光系统中产生光学涡旋。放大和压缩后，在梁路径中以倾斜的入射角使用离轴螺旋相后视镜，从而使几乎所有激光系统都会产生高功率光学涡旋。通过修改螺旋相螺旋的方位角梯度，可以使用离轴配置，并使用离散的螺旋楼梯通过简单模型来证明。这项工作介绍了低功率和高功率激光系统中轴心螺旋相反射镜的设计，制造和实施。
In this work, we present a novel and practical method for generating optical vortices in high-power laser systems. Off-axis spiral phase mirrors are used at oblique angles of incidence in the beam path after amplification and compression allowing for the generation of high-power optical vortices in almost any laser system. An off-axis configuration is possible via modification of the azimuthal gradient of the spiral phase helix and is demonstrated with a simple model using a discrete spiral staircase. This work presents the design, fabrication, and implementation of off-axis spiral phase mirrors in both low and high-power laser systems.
