NASA 1996 SBIR Phase I


PROPOSAL NUMBER : 96-1 13.07-3772

PROJECT TITLE : COMPOSITIONALLY TUNED SOLID-STATE LASER MATERIALS

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

This proposed SBIR project is to develop new solid-state laser materials where the absorption and emission spectra are compositionally tuned to allow free-run lasing at the desired wavelength. This is accomplished by precisely varying the lattice constant of a given material thereby shifting the energy levels of the active dopant ion. This research project will also explore the potential of this concept for systematic control of energy levels for optimization or quenching of upconversion processes. There are three specific technical objectives for this project. The first will be the development of a material that will allow free running laser operation at 944.1 nm for use in Lidar systems designed for remote sensing of atmospheric water vapor. The second objective will be the development of a material capable of operation at 2.027 mm which corresponds to a spectral region of low atmospheric absorption for use in Lidar systems for long range remote sensing of wind profiles and atmospheric contaminants. The third objective will be to explore Er doped materials to optimize lasing wavelengths in the 1.5 mm - 1.6 mm and 2.6 mm - 3 mm regions.
POTENTIAL COMMERCIAL APPLICATIONS
Materials developed through this research have POTENTIAL COMMERCIAL APPLICATION in a variety of LIDAR systems including those for wind vortex and wind shear measurement, remote sensing of pollutants, remote sensing of water vapor, and gas stream analysis. These materials also have potential for application in wavelength specific medical lasers
