摘要

Toothed apodizing stops fabricated by laser cutting of the volume or surface of a transparent dielectric plate that possesses a radiation strength of up to 22 J/cm(2) have been developed and investigated. It is shown that picosecond laser pulses can be used to shape teeth to within an 8-mu m accuracy on K8 glass plates with one-sided or two-sided antireflection coatings. The shaping of the spatial beam profile by toothed stops in an apodizing system has been investigated. (C) 2016 Optical Society of America.
