Abstract :
On the basis of accurately measured refractive indexes, the authors have obtained the Sellmeier´s equations for flux grown KTiOPO 4 (KTP) crystal and used them to calculate the phase matched angles (θm, φm) and effective nonlinear coefficients (deff) for type I and III second harmonic generation (SHG) and sum frequency mixing (SFM) of radiations at 1.0795 and 1.3414 μm. The optimum phase matching conditions for 1.0795 and 1.3414 μm SHG are that θm=86.88 and 58.88°, respectively, in an XZ plane (φ=0) and for SMF of 1.0795 and 1.3414 μm in the same plane 76.02°. The corresponding deff values calculated from θ ms are 18.07×10-9 and 17.42×10-9 esu
