Innovative Eye-Safe Wavelength High Power Fiber Laser

High power fiber lasers have made significant progress in the last several years. Ten kW of diffraction-limited output power at 1 micron from one single mode fiber has been demonstrated. Department of Defense (DoD) needs 100s of kW for missile defense as well as for protection against rockets, artillery, and mortars (RAM). There is serious concern about current 1 micron fiber laser system potentially causing collateral eye damage due to scatter off of target surfaces. AdValue Photonics proposes to develop an innovative eye-safe single mode fiber laser with output power greater than 5kW using our proprietary glass fibers, and scale up the total power to 100s-kW with good beam quality using an innovative beam combining technique. In Phase II we shall further optimize erbium doped double cladding fiber, demonstrate cladding pumped fiber laser with slope efficiency greater than 85%, demonstrate output power of 500W, and design the proposed 100kW fiber laser system.
