Abstract

IN THE PREVIOUS RESEARCH WORK, THE FIRST SINGLE ELEMENT GaP 2-D ACOUSTO-OPTIC LASER BEAM DEFLECTOR WAS DESIGNED AND FABRICATED FOR USE IN AN OPTICAL-BASED COMPUTING SYSTEM, WITHOUT THE USE OF MIRRORS. CURRENTLY, A MIRRORLESS HIGH EFFICIENCY 10.6 MICROSECOND TWIN ACOUSTICAL BEAM STEERER (TABS) DEVICE IS BEING DEVELOPED SUPERIOR TO THE ACOUSTO-OPTIC BEAM STEERER PREVIOUSLY DEMONSTRATED. ANTICIPATING USE OF THE 2-D TABS DEVICE IN STRATEGIC DEFENSE APPLICATIONS, THE ADVERSE EFFECT OF LARGER OPTICAL POWERS UPON THE DEVICE IS BEING EVALUATED. A SINGLE ELEMENT 2-D TABS DEVICE DESIGNED FROM GERMANIUM (Ge) IS BEING FABRICATED AND TESTED. A 1-D LASER BEAM STEERER IS BEING DESIGNED FROM SINGLE CRYSTAL TELLURIUM (Te); Te IS EXPECTED TO PERFORM FIVE TIMES BETTER THAN CONVENTIONAL Ge. LARGE SINGLE CRYSTALS OF Te ARE BEING GROWN. BENEFITS OF A 2-D ACOUSTO-OPTIC HIGH POWER LASER BEAM DEFECTOR OVER CONVENTIONAL MIRRORS INCLUDE GREATER SPEED, LIGHTER WEIGHT, SMALLER SIZE, LOW POWER CONSUMPTION, AND LOWER COST.
