THE GROWTH AND DEVELOPMENT OF A (GAP)1-X(ZNS)X-BASED MATERIAL IS BEING ENGINEERED TO PREPARE AN UTEROPOLAR, DIRECT BANDGAP MATERIAL. THIS TYPE OF MATERIAL WITH BANDGAP IN EXCESS OF 2.6 EV CAN BE EMPLOYED IN BLUE LIGHT-EMITTING DIODES, AND IN UV DETECTORS CAPABLE OF SUPERIOR PERFORMANCE COMPARED TO SILICON, IN HIGH TEMPERATURE, HIGH RADIATION ENVIRONMENTS SUCH AS IN EARTH ORBIT AND PARTICLE ACCELER ...

AstroPower is developing a two-junction monolithic tandem solar cell composed of (AlxGa1-x)0.51In.49P lattice matched to GaAs for use as the top cell in a three-junction, two-terminal tandem stack. This tunable bandgap material system is capable of current matching, at 2.03eV, in a two-junction monolithic tandem solar cell two terminal design of (AlxGa1-x)0.51In0.49P/GaAs yielding a best case pred ...

Currently, dye lasers use dyes that are dissolved in a solvent and then flowed througha cell or jet. Although this is a successful solution to achieve a working dye lser system with tunability over a broad spectrum, there are also significant limitations to the full realization of the potentail ofthis medium. Primarily, liquid hosts adversely affect the thermodynamic, spectroscopic, and kinetic pr ...

COMPACT BLUE-GREEN LASERS ARE REQUIRED FOR APPLIATIONS IN OPTICAL DATA STORAGE, REPROGRAPHICS, AND BIOMEDICAL DIAGNOSTICS. IR-PUMPED VISIBLE UPCONVERSION LASERS ARE A PARTICULARLY PROMISING CLASS OF BLUE-GREEN LASERS. IN ORDER FOR THE DEVELOPMENT OF IR-PUMPED VISIBLE LASERS TO PROGRESS BEYOND ITS CURRENT LEVEL OF DEVELOPMENT, A RELIABLE SOURCE OF BARIUM YTTRIUM FLUORIDE MATERIAL IS REQUIRED. THIS ...

CREATING EQUAL OPPORTUNITIES IS THE PRIMARY INTENT OF THE AMERICANS WITH DISABILITIES ACT. THE HELPING HANDS VIDEO WILL PROVIDE SPECIFIC SOLUTIONS ON HOW TO CREATE THESE OPPORTUNITIES. THIS THIRTY MINUTE VIDEO WILL BEGIN WITH A SUMMARY OF THE AMERICANS WITH DISABILITIES ACT AND THEN DEMONSTRATE HOW TO MODIFY THE WORK ENVIRONMENT PHYSICALLY TO BE ACCESSIBLE AND EFFECTIVE IN REDUCING THE BARRIERS TO ...

THIS PROGRAM WILL DEMONSTRATE HIGH SPECIFIC POWER, LIGHTWEIGHT, FLEXIBLE, THIN SILICON SOLAR CELLS. THESE SOLAR CELLS CAN BE DIRECTLY SUBSTITUTED FOR EXISTING STATE OF THE ART SILICON SOLAR CELLS WITH THE EFFECT OF SIGNIFICANTLY IMPROVING SPECIFIC POWER, POWER/AREA, AND POWER SUPPLY LIFE. THE PROPOSAL DESCRIBES A LIGHTWEIGHT, FLEXIBLE, HIGH-PERFORMANCE, ULTRA-THIN SILICON SOLAR CELL THAT INCORPORA ...

IN PHASE I OF THIS PROPOSAL WE WISH TO INVESTIGATE A NEW MATERIAL B-BBO AS HIGH AVERAGE POWER AND HIGH PEAK POWER ELECTRO-OPTIC INTRACAVITY POCKELS CELL. SUCH A DEVICE IS REQUIRED FOR DIODE-PUMPED Nd:YAG SOLID-STATE LASERS FOR HANDLING CIRCULATING POWERS UPTO 100 WATTS. PRESENT MATERIALS ARE LIMITED WITH SERIOUS THERMAL HEATING AND SUBSEQUENT DAMAGE DUE TO LINEAR OPTICAL ABSORPTION PROBLEMS. CRYST ...

The specific aim of this Phase I study is to study the feasibility of a new low cost technology for high resolution, high sensitivity, Single Photon Emission Computed Tomography (SPECT). The principal objective of this new technology is to achieve about a factor of six higher spatial resolution (1.5mm compared to 10mm) than achieved with the existing systems. We propose using the technology we hav ...

ASTROPOWER PROPOSES TO DEVELOP A LIGHTWEIGHT, HIGH PERFORMANCE, ULTRA-THIN ELECTROSTATICALLY BONDED GaAs SOLAR CELL WITH COPLANAR BACK CONTACTS. THE INNOVATIVE DESIGN INCORPORATES LIGHT TRAPPING, ADHESIVELESS COVER SLIDE BONDING, AND ELIMINATES GRID SHADING. THIS NOVEL DEVICE WILL EXHIBIT INCREASED EFFICIENCY AND SPECIFIC POWER DUE TO THE HIGHER OPEN CIRCUIT VOLTAGE AND SHORT CIRCUIT CURRENT OBTAI ...
