Abstract
We show that centrosymmetric natural hyperbolic media such as hexagonal boron nitride exhibit a bulk second-order nonlinear response, leading to second-harmonic and sum- and difference-frequency generation with efficiencies comparable to those of established nonlinear optical crystals such as potassium dihydrogen phosphate.
