We report the generation of Bessel-Gauss beams of high conical angle, up to 35 deg, using reflective off-axis axicons and a magnification optical system. We experimentally characterize the beams with three-dimensional scans. The high precision of fabrication of the axicons in the vicinity of the axicon singularity allows us to generate a beam with intensity distribution close to analytical description.
我们报告了使用反射式离轴锥镜和放大光学系统生成高达35度高锥角的贝塞尔-高斯光束的情况。我们通过三维扫描对光束进行了实验表征。锥镜在锥镜奇点附近的高精度制造使我们能够生成强度分布接近解析描述的光束。
