NASA applications are in systems requiring compact, efficient, reliable, moderate-energy, nanosecond-pulsed lasers. For planetary exploration, these applications are in LIBS/Raman/LIF systems used for planetary surface characterization and in lidar systems for atmospheric measurements of aerosol concentrations and distributions, as well as precision ranging for planetary surface mapping from satellites and other spacecraft. The laser we propose to develop is compact, efficient, rugged and reliable, making it ideal for planetary missions. Given the high sensitivity of launch requirements to SWaP considerations and to reliability, we feel that the proposed laser source is uniquely positioned for standoff LIBS based missions. Other NASA mission profiles or applications that would benefit from generically small, light- weight, low power laser sources would be equally well served. Commercial applications are in portable LIBS systems to replace the current bulky, inefficient, and less reliable lamp-pumped lasers now employed. LIBS, besides having numerous scientific applications in materials characterization, can also be used in industrial applications for process control through monitoring of exhaust streams, analysis of pharmaceuticals, profiling of metals, composition determinations of minerals in mining and detection of contamination in the environment. There are numerous applications for green lasers besides LIBS that require minimized SWaP. Green Illuminators with sufficiently high beam quality to enable long atmospheric transmission suffer from excess size and weight. The proposed laser would produce the required beam quality with a SWaP advantage of near factor 2. Green lasers can be use in the Non-Lethal Laser Dazzler field. Dazzlers, are most effective in green due to the eye's high sensitivity in the green spectral region but also require the most careful spatial beam profile control to insure that both spatially and temporally, the laser energy never reaches or exceeds the damage threshold of the eye. Q-Peak's advantage would be in having developed an extremely small, compact, simple, and rugged technology for generation of single mode laser pulse. This laser device will be much better suited for fieldable systems than present products both on SWaP, mode profile, and affordability considerations.
