We demonstrate highly efficient performance (quantum efficiency as great as 80%) of a degenerate three-beam-pumped optical parametric amplifier (OPA). Such an OPA exhibits a parametric combining effect, as the signal gains its energy from all three pump pulses. The efficiency of the parametric amplification process is defined only by a triple phase-matching geometry and is insensitive to the phase relationship of the pump pulses. We also show that OPA operation is not affected by the number of pump pulses in terms of the energy conversion and the temporal characteristics of the amplified pulse.
