High power CO2 laser energy detector

Abstract
A CO2 laser energy detector is described which uses the pressure rise generated in a vaccum cell by gaseous infrared absorption to provide linear energy detection over many decades, good responsivity, wide aperture, and in−line beam monitoring. Nonadiabatic pressure measurements resulting when the beam size is less than the cell aperture are discussed.
