TECHNICAL ABSTRACT (LIMIT 200 WORDS)
The purpose of this program is to develop a compact and efficient ultraviolet laser for use in space-based uv-Raman instruments. The basis for this system will be a diode-pumped neodymium-yttria (Nd:Y2O3) ceramic laser which is frequency-quadrupled to generate uv light at 237nm. The unique combination of a low-cost and robust ceramic laser with efficient 4th harmonic generation will provide an ideal ultraviolet source for NASA missions to planets and moons in the Solar System.

POTENTIAL NASA COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
In addition to uv-Raman applications for the 237nm 4th harmonic, an efficient 947nm Nd:Y2O3 laser could be used for NASA water vapor Lidar programs. A frequency-tripled laser at 315nm could be used for ozone Lidar applications. In general, ceramic laser materials provide attractive alternatives to single-crystals for a variety of NASA requirements.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
Frequency-doubled Nd:Y2O3 lasers in the 450-475nm range can be used for display applications and in bio-medical instruments such as cell sorters, flow cytometers, and DNA sequencers. Frequency-tripled lasers in the 305-315nm range will be used for stereo-lithography and materials processing such as micro-machining. Frequency-quadrupled lasers near 237nm can be used for detection of chemical and biological agents.
