摘要
针对神光-Ⅲ原型装置使用的光学元件,基于国内光学元件加工现状,结合空间频段的概念,对高功率固体激光驱动器所需光学元件不同的面形评价参数进行了阐述.结合对激光远场焦斑的影响,对面形评价参数的重要性进行了举例说明.提出了面形的综合评价方式,全面界定面形各项评价参数,对光学元件的评价具有一定的参考价值.
Abstract
Based on the optics manufacture actualitys in our country, different parameters used to value the optics profile for high power laser drivers are expatiated with the concept of spatial wavelength region. At the same time, the importance of each parameter is illustrated through its influence on farfield focus distribution. This article put forward the integrative evaluate mode for profile and prescribed all these parameters roundly. It gives a reference to value the optics profile.
