Second-harmonic and sum-frequency generation to 4950 and 4589 AA in KTP

Abstract

KTiOPO/sub 4/ (KTP) has been found to be phase matchable for type-2 second-harmonic and sum-frequency generation down to 4950 and 4589 AA, respectively. Sellmeier's equations which are highly accurate from 1.152 mu m to 4590 AA are reported.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
