BBO AND LBO CLASS MATERIALS WERE STUDIED FOR POSSIBLE APPLICATION AS UV-SENSITIVE PHOTOREFRACTIVE MATERIALS. UNDOPED SAMPLES OF BBO AND LBO WERE DOPED BY HIGH TEMPERATURE DIFFUSION WITH VARIOUS TRANSITION METAL SPECIES TO DETERMINE THEIR SUITABILITY FOR STORING HIGH EFFICIENCY HOLOGRAPHIC GRATINGS. OXIDATION AND REDUCTION HEAT TREATMENTS WERE CARRIED OUT ON THE RESULTING MATERIALS TO OPTIMIZE TH ...

THIS NATION HAS MORE THAN 11 MILLION MANHOLES WHICH NOW NEED, OR SOON WILL NEED, TO BE REHABILITATED. CURRENT TECHNIQUES ARE EITHER TOO COSTLY OR DO NOT LAST. THIS RESEARCH SPEAKS TO THIS PROBLEM THROUGH DEVELOPMENT OF AN INNOVATIVE TECHNIQUE OF RESTORING MANY OF THESE STRUCTURES AT LESS THAN HALF THE COST OF THE RELIABLE METHODS AVAILABLE TODAY. THE CONCEPT USES A NEWLY DEVELOPED APPLICATOR WH ...

IN AN EFFORT TO REACH HIGHER POWERS, LASER RESEARCHERS HAVE DEVELOPED LARGER AND INCREASINGLY COMPLEX DEVICES. AN ALTERNATE SCALING APPROACH IS TO COMBINE THE OUTPUT POWER OF MANY SIMPLE LOW-POWER LASERS IN AN ARRAY. MICROLASERS ARE THE PERFECT ARRAY ELEMENTS BECAUSE THEY ARE MASS-PRODUCIBLE AND HAVE POLARIZED, SINGLE-FREQUENCY, DIFFRACTION-LIMITED OUTPUTS. RESEARCHERS HAVE DEVELOPED A UNIQUE M ...

THE OBJECTIVE OF THIS RESEARCH IS TO EXPLORE THE FEASIBILITY OF DEVELOPING A HIGH INTENSITY UV EXCIMER SOURCE FOR THE DEMANDING REQUIREMENTS OF THE SEMICONDUCTOR MANUFACTURING AND MATERIALS PROCESSING INDUSTRY. EMERGING PROCESSING TECHNOLOGIES NOT REQUIRING A COHERENT SOURCE INCLUDING UV WAFER CLEANING AND PHOTO CVD WILL REQUIRE VERY HIGH UV INTENSITIES OVER LARGE AREAS (100 MW/CM2) CURRENTLY ONL ...

POLYMERIC MATERIALS ARE USED EXTENSIVELY IN A MULTITUDE OF APPLICATIONS DUE TO A UNIQUE BALANCE OF COST AND STRUCTURAL PROPERTIES. HOWEVER, WHERE THERMAL APPLICATIONS ARE CONCERNED, THE UTILIZATION OF POLYMERIC MATERIALS IS EXTREMELY LIMITED DUE TO POOR THERMAL TRANSFER. STRUCTURAL POLYMERS TYPICALLY EXHIBIT THERMAL CONDUCTIVITIES ORDERS OF MAGNITUDE LOWER THAN MOST METALS AND CERAMICS. PARTICU ...

THE DEVELOPMENT OF COLD ELECTRON EMITTER TECHNOLOGY HAS THE POTENTIAL FOR BROADLY IMPACTING THE RAPIDLY GROWING AREA OF ELECTRON SPECTROSCOPY. COMMERCIALLY AVAILABLE INSTRUMENTATION SUCH AS AUGER SPECTROMETERS TYPICALLY EMPLOY THERMIONIC ELECTRON SOURCES WHICH RESTRICT THEIR SCOPE OF USE THROUGH FILAMENT HEATING EFFECTS AND THERMAL CRACKING OF GASES ON FILAMENTS. THESE INSTRUMENTS ARE NOT CAPABL ...
