Abstract
THIS PROPOSAL DEALS WITH THE DESIGN OF HIGH PULSED POWER DIODE LASER ARRAYS AND THE DEVELOPMENT OF FABRICATION TECHNIQUES FOR ACHIEVING SUCH ARRAYS. DURING THE FIRST PART OF THIS PHASE I EFFORT WE WILL CRITICALLY REVIEW EXISTING DESIGNS OF EDGE-EMITTING AND SURFACEEMITTING LASER ARRAYS. THERE HAS BEEN AN EVER-INCREASINGLY RAPID RATE OF DIODE LASER ARRAY DEVELOPMENTS IN RECENT YEARS, STIMULATED IN LARGE PART BY THE SUCCESSFUL ACHIEVEMENT OF THE QUANTUM WELL (QW) LASER, WITH ITS INHERENT SUPERIORITY IN TERMS OF THRESHOLD CURRENT, OUTPUT POWER, AND TEMPERATURE DEPENDENCE. SPIRE WILL WORK CLOSELY WITH THE NAVY AND ORDNANCE MANUFACTURERS TO EXPLORE LASER ARRAY DESIGNS BEST SUITED FOR THE REQUIRED PURPOSES. AS THE MOST IMPORTANT PART OF THIS PHASE I PROGRAM, SPIRE WILL DESIGN AN ARRAY BEST SUITED FOR ACHIEVING REQUIRED OBJECTIVES OF HIGH PEAK PULSED POWER. RECENT DEVELOPMENTS IN HIGH POWER SURFACE-EMITTING, MULTIPLE QUANTUM WELL (MQW) LASERS INDICATE THAT THIS TECHNOLOGY MAY BE IDEALLY SUITED FOR THIS PURPOSE, AND WE INTEND TO EXPLORE THIS TECHNOLOGY IN GREAT DETAIL. THE MOCVD EPITAXIAL LAYER GROWTH TECHNOLOGY, FOR WHICH SPIRE HAS A WORLD-WIDE REPUTATION OF ACHIEVEMENT, WILL FORM THE BASIS OF THE PROPOSED PROGRAM. LASER ARRAY DESIGNS WILL BE COMPATIBLE WITH THIS TECHNOLOGY. SOME PRELIMINARY LASER ARRAY FABRICATION STUDIES RELATED TO THE ARRAY DESIGN WILL ALSO BE CARRIED OUT. THE PHASE I EFFORT WILL BE CARRIED OUT WITH THE OBJECTIVE OF UTILIZING A PHASE II PROGRAM TO IMPLEMENT THE DESIGN PARAMETERS DEVELOPED DURING PHASE I.
