Gain spectrum of an optical parametric amplifier with a temporally incoherent pump.
We experimentally investigate the performance of a fiber optic parametric amplifier pumped with a temporally incoherent pump. The measured gain curves are compared with both a simple theory capable of predicting the maximum attainable mean incoherent parametric gain and full numerical simulations of the nonlinear Schrödinger equation. Parametric gain slopes seven times higher than that of an equivalent coherently pumped parametric amplifier are reported.
