Abstract
MANY TACTICAL AND STRATEGIC REMOTE SENSING APPLICATIONS WOULD BENEFIT FROM A NARROW-BAND EFFICIENT EYESAFE SOLID-STATE LASER SOURCE. RECENT PROGRESS IN DIODE LASER-PUMPING OF THULIUM (TM)- AND TM:HOLMIUM (HO)-DOPED SOLID-STATE LASERS HAS DEMONSTRATED THAT LOW POWER CW DEVICES CAN OPERATE AT OR NEAR ROOM TEMPERATURE VERY EFFICIENTLY. ANALYSIS INDICATES THESE LASERS SHOULD ALSO WORK WELL UNDER Q-SWITCHED OPERATION AT ROOM TEMPERATURE. AT THIS TIME, DEMONSTRATIONS OF Q-SWITCHING THESE MATERIALS UNDER DIODE-LASER-PUMPING HAVE NOT BEEN REPORTED. DURING THE PROPOSED PHASE I EFFORT, WE WILL PERFORM ANALYSIS AND EXPERIMENTS TO PROVE FEASIBILITY FOR THE DEVELOPMENT OF A PRACTICAL 10 MJ/PULSE 200-HZ DIODE LASER-PUMPED Q-SWITCHED TM:YAG OR TM:HO:YAG LASER OPERATING AT ROOM TEMPERATURE OR COOLED SLIGHTLY BELOW ROOM TEMPERATURE USING THERMO-ELECTRICCOOLERS. THE FEASIBILITY EXPERIMENTS WILL INCLUDE A MATERIAL OPTIMIZATION PROGRAM IN WHICH THE Q-SWITCHED PERFORMANCE OF SEVERAL TM:YAG AND TM:HO:YAG CRYSTALS WITH VARYING TM AND HO CONCENTRATION WILL BE COMPARED.
