Abstract

We report 6 kW pump limited power handling in a 7+1 to 1 Pump-Signal Combiner. The high pump transmission efficiency of 98% and optimal thermal management of the combiner package enables a low thermal slope of 0.0037 C/W measured up to 6 kW of pump power. The low thermal slope allows for a potential 9 kW pump power handling capacity of the 7+1 to 1 combiner.
