Abstract

The key techniques of spatial filter matrix used in large laser facility such as super-long-distance beam transmission

beam control

beam quality control

stability of supporting structure

adjustment accuracy of all coupling glasses

stability of glass mounts

off-axis adjustment are studied. This paper surveys current technology of spatial filters

determines the specifications of the system

and finally provides a comprehensive solution for the structure design of spatial filter by using "Pro/E" software program in the 3-D simulation model of spatial filter matrix. The key components and specifications are analyzed carefully

and new structure design and techniques are employed. The rigidity

strength

and vibration modes of the structure are analyzed using "ANSYS" software program. The structure has been optimized by bidirectional embedding of finite element method and CAD. To seek the proof for the equipment structural flexibility

it has been tested with a slight shock to check the components and units

which has significant influence on the structure stability.
