High Power fiber lasers represent the fastest growing segment of the over $2B per year material processing market. A kW class fiber laser that is considerably smaller, and much lower cost will be a successful competitor in this market and will have a very good chance of gaining market share. The proposed fiber laser technology is extend able to the eyesafe portion of the spectrum allowing further penetration into these portions of the laser processing market. Laser processing is a small portion of the over $30B per year material processing market that can be further penetrated as the cost of these systems is reduced and flexibility of these systems is increased. High Power Fiber amplifiers that are compact, robust, reliable and low cost can provide the basis of many potential NASA applications from Uplink beacons that are either terrestrial, airborne or space based, and also can provide the basis of high power lasers for Lidar, LIBS, and other remote sensing applications. This technology is also extend able to pulsed regimens and different wavelenghts as well
