Multi kW Etched Air Taper Counter Pump Fiber Combiner
Optical Engines has developed and demonstrated a high power pump combiner in the co-propagating direction with 94.5% pump efficiency and a 20dB PER with zero brightness drop. This combiner has been tested for extended periods (approx 1 Hr) with 1.5kW of pump power with no degradation. This was combining into PM PCF Yb doped gain fiber. Optical Engines unique Etched Air Taper Technology will be used to extend this highly successful design into the counter pumped direction. For the Phase 1, Optical Engines will develop and demonstrate a Etched Air Taper counter pump combiner into 25/400 Yb doped Step Index fiber with 6 200um pumps and will test the device to 1.5kW. In the Phase II program this design will be extended to PCF fiber and tested to over 3kW.
