Abstract

This paper reports on a new type of modulator which can be used for many applications of intense CO₂ laser radiation. The modulator is based on the principle of the Fabry-Perot interferometer and acts as a beam splitter with variable reflectivity which is placed outside the laser cavity. By means of the tuning of the spacing between the two plane parallel interferometer plates the intensity of the transmitted as well as the reflected part of the incident laser beam can be modulated. The principle of construction, typical properties and some characteristic applications are given.
