Abstract

A device which will attenuate a 10.6 micron wave length light beam from 1% of the original intensity. The original intensity can be as high as 1000 watts. The unit is an absorption cell of variable path length filled with a gaseous mixture of sulfur hexafluoride and nitrogen at a total of one atmosphere. Power attenuation is accomplished by SF.sub.6 - absorption and energy exchange to N.sub.2 or walls. The output is controlled by a motor which moves one of the two windows thus changing the absorption path.
