Abstract

We describe spatial filters used in an Nd:glass laser with an output pulse energy up to 300 J and a pulse duration of 1 ns. This laser is designed for pumping of a chirped pulse parametric amplifier. We present data required to choose a shape and diameter of spatial filter lens, taking into account aberrations caused by spherical surfaces. Design features of spatial filters and the procedure of them adjustment are discussed in details.
