Abstract

On the basis of a new topological classification of phase-matching (PM) direction loci in biaxial acentric crystals, the PM Loci of Potassium titanyl phosphate (KTP) crystal in second harmonic generation (SHG) and sum-, difference- frequency generation (SFG,DFG) are presented over its entire transparency region for the first time. The result shows that there are totally 5 loci and 7 transitions for SHG, 8 Loci and 15 transitions for SFG/DFG. The weak temperature dependence of KTP yields that the noncritical PM (NCPM) of SHG varies slowly in the range of 20-300degC.
