Abstract: An apparatus includes a plurality of front-end nonlinear optical crystals and a plurality of back-end nonlinear optical crystals. The front-end nonlinear optical crystals are arranged in a chain and are configured to amplify a received signal. The back-end nonlinear optical crystals are arranged in the chain after the front-end nonlinear optical crystals and are configured to further amplify the received signal and generate an amplified signal. The back-end nonlinear optical crystals are made from a different nonlinear optical crystal than the front-end nonlinear optical crystals.
