Multi-Wavelength Low-Power Solid State Lasers for Space Based Laser Systems

"Abstract: The emergence of space-based lasers as a viable alternative for ballistic missile destruction in space has started a flourish of activity aimed at the development and testing of components and systems required for this application. Currentschedule for the completion of these tests is very tight, and the lack of some special items not yet commercially or otherwise available calls for their early and accelerated development. A low-power laser device is needed for a high fidelity low-powerrealization of a beam with similar characteristics to the one produced by the high power HF laser. This beam is used for emission optics adjustments to precisely aim and focus the high power radiation on the target. Several concepts will be proposed andanalyzed. This effort will lead to the design, testing and space qualification of the required lasers. The multi-wavelength and tunability capabilities provided by these lasers, within a power range of 1-10 watts, are very valuable characteristics fortheir use in other fields such as lidar applications. The novel solid-sate laser technology to be developed will decrease the size, weight and cost of high-power diode-pumped lasers. These reductions will make affordable applications including materialsprocessing and large area displays"
