Holographic transmission cylindrical mirror stretcher

The invention discloses a holographic transmission cylindrical mirror stretcher, which belongs to the field of ultra-short laser, can be used for the stretching process of the ultra-short laser, and specifically comprises a compensation assembly, a grating assembly and a lens assembly, the grating assembly comprises a first grating and a second grating, and the lens assembly comprises a concave cylindrical reflector, a convex cylindrical reflector, a first plane reflector and a ridge mirror. According to the invention, the image transmission system composed of cylindrical lenses is used for pre-compensating the image transmission relation of the cylindrical mirror stretcher for the first time, the problem that the image transmission relation of the existing cylindrical mirror stretcher is inconsistent in a two-dimensional space is solved, and laser with high spatial quality can be output. 本发明公开了一种全像传递的柱面镜展宽器，属于超短激光领域，可用于超短激光的展宽过程，具体包括补偿组件、光栅组件和镜片组件；光栅组件包括第一光栅和第二光栅，镜片组件包括凹柱面反射镜、凸柱面反射镜、第一平面反射镜、屋脊镜。本发明首次提出了采用柱透镜
