We have already sampled mederate power "virtual ring" laser prototypes for potential defense applications. These include acoustic sensor system important for homeland defense. This application benefits from the low phase noise, low RIN and the outstanding frequency stability of the Ethernal laser. This and other applications can benefit from further R&D of our base-line technology. In addition, a high power Ethernal laser system can be importtant for coherent free space communications. LIDAR sytems are also needed commercially for measurement of wind speed and vortices. Coherent laser radar (LIDAR) use heterodyne detection by mixing the laser light scattered from a remote target with a reference local coherent laser oscillator. This technique offers high sensitivity as well as providing detailed phase and velocity information important for many current and future NASA missions. These include: velocimetry, wind sensing and aerosol particle size distribution. In addition, coherent lasers are important for deep space and inter-satellite communications systems especially at 1.06 ?m.
