The objective of the program is to explore various techniques using GaAs epitaxial thin films as the active elements for electrooptic modulation of the 10.6 micrometer CO2 laser radiation. The advantages as well as the limiting factors concerning the use of thin films to perform phase and polarization modulation or switching of infrared laser radiation are investigated. The results of this program shall provide useful information concerning the possible use of GaAs thin films to replace bulk materials for electrooptic modulation of infrared laser radiation. Furthermore, results of this program may provide a guideline to the design of the master oscillator by taking the advantage of thin film modulator to yield the necessary wave envelope and bandwidth required for the high power pulsed CO2 laser imaging radar system.
