Abstract

STUDIES HAVE SHOWN THAT ULTRAVIOLET WAVEGUIDE LASER PHASED ARRAYS MAY BE AMPLIFIED WITHOUT DEGRADING COHERENCE AND CAN BE EASILY INJECTION LOADED, MAKING SUITABLE FOR RADAR APPLICATIONS. ADDITIONALLY, THEY ARE CHARACTERIZED BY EFFICIENT HIGH REPETITION RATES WITH LONG OPTICAL PULSE DURATION. IN THIS PROJECT, SMALL TWO DIMENSIONAL XENON-CHLORIDE (XeCl) LASER ARRAYS, EXCITED BY ELECTRODELESS MICROWAVE DISCHARGES, ARE BEING CONSTRUCTED AND TESTED. THE SMALL ARRAYS WILL BE USED TO DEMONSTRATE POWER SCALING, PHASELOCKED OPERATION, AND INDEPENDENT PHASE CONTROL OF ARRAY ELEMENTS. IN ADDITION TO RADAR, WAVEGUIDE EXCIMER LASER ARRAYS HAVE POTENTIAL APPLICATION IN MATERIALS PROCESSING, DIRECT WRITE PATTERNING OF SEMICONDUCTOR MATERIALS, MICROFABRICATION, LASER SURGERY, AND ANALYTIC INSTRUMENTATION.
