Abstract

Resonance-enhanced sum-frequency generation is introduced as a novel tool for investigation of magnetically ordered compounds. A tunable laser at frequency ω1 is used to excite an intermediate electronic transition resonantly while a second laser at frequency ω2 is used to scan the nonlinear spectrum at ω1 + ω 2. The technique is particularly useful for investigation of centrosymmetric compounds since resonance enhancement at ω1 leads to large nonlinear signals even in the case of weakly allowed nonlinear processes. The technique is demonstrated on antiferromagnetic NiO and KNiF 3 and also shown to be useful for investigation of samples with large thickness or absorption.
