Paper Abstract

We present a numerical model of a multi-crystal approach that increases the quantum efficiency of a parametric amplifier. Here is a two-crystal approach where the second stage crystal uses the signal energy from the first stage to amplify the desired idler wavelength. The numerical model allows for arbitrary input beam profiles and it can accommodate multiple crystals and optical elements. In this study a pair of PPLN crystals was modeled leading to more than double the idler output energy. The maximum M2 value for the output idler beam calculated was 5.2.
