We demonstrate ~50% efficient adiabatic optical parametric amplification in bulk crystals by introducing temperature-gradient phase-matching. We provide details on the choice of temperature profile that maximizes conversion efficiency and increases bandwidth to over 300 nm.

Abstract
We demonstrate ~50% efficient adiabatic optical parametric amplification in bulk crystals by introducing temperature-gradient phase-matching. We provide details on the choice of temperature profile that maximizes conversion efficiency and increases bandwidth to over 300 nm.
