Ultra Compact Multi kW Fiber Amplifier Platform
ABSTRACT: During the phase 1 program, Optical Engines, Inc. has demonstrated the key components necessary to create an ultra compact multi kW Yb based PM PCF amplifier. These components include a 3 fiber coupled laser diode stack with an aggregate power output of over 1200 W at 976nm, an etched air taper all fiber combiner in a 6+1 to 1 configuration with 94.4% pump efficiency, over 90% core signal efficiency, 20dB PER, and has been power tested to 1.5kW. These components, along with a 40um Yb PM PCF core, 500um Air clad cladding fiber have been combined to create an all fiber amplifier of over 1kW. In the Phase 2 program these components will be combined to create a TRL 5 ready, narrow band amplifier in the multi kW range. BENEFIT: The development of a ultra compact multi kW amplifier module will have the impact of providing a common platform for defense and industrial applications allowing for economies of scale and economies of scope.
