TECHNICAL ABSTRACT (LIMIT 200 WORDS)
Laser induced breakdown spectroscopy (LIBS) is a versatile tool for in situ substance characterization. Existing LIBS instruments are not compact enough for space applications. Major obstructs for miniaturization are from: high voltage Q-switch based pulse laser, inefficient light collection system and bulky high sensitive array-detection. Based on a revolutionary low-voltage Q-switch technology and high efficient laser delivery and light collection scheme, Boston Applied Technologies proposes to develop an ultra-compact high sensitive LIBS instrument for NASA application. The laser featured fast and dual-pulse Q-switch with low switching voltage, ultra reliable fiber-ring cavity design, and high efficient laser-diode pumping. The low switching voltage also brings the advantage of reducing the complexity of the electronic driver design, which is a big chunk in existing electro-optical or acoustic-optic Q-switching lasers. The required ablation energy can be significantly reduced due to high efficiency of the proposed system. The resultant LIBS instrument will be compact, cost-effective and reliable. It will be capable of withstanding operation in space and planetary environmental extremes, which include temperature, pressure, radiation, and impact stresses.

POTENTIAL NASA COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
This very compact LIBS instrument can be space qualified for versatile in situ substance characterization at key places in the solar system, and the return of materials from them for later study on the Earth. It is well suited for many NASA's planned and potential solar system exploration missions, especially for life (water)-finding on other planets and mineralogy analysis of surface and subsurface materials.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
This versatile instrument has wide range applications such as environmental hazards analysis, explosive material identification for security, and geochemistry characterization on the Earth etc.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
