Abstract:

This report describes a device which will attenuate a 10.6 micron wave length light beam from 1-95 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 SF6-absorption and energy exchange to N2 or walls. The output is controlled by a motor which moves one of the two windows thus changing the absorption path.
