B. Boulanger et al., RELATIVE SIGN AND ABSOLUTE MAGNITUDE OF D(2) NONLINEAR COEFFICIENTS OF KTP FROM 2ND-HARMONIC-GENERATION MEASUREMENTS, Journal of the Optical Society of America. B, Optical physics, 11(5), 1994, pp. 750-757
We determine the absolute magnitude of the d(ij)(2) coefficients of KT
P, using type-I and type-II phase-matching second-harmonic-generation
efficiency measurements: \d15 (0.532 mum)\ = 1.4 +/-0.07 pm/V, \d24 (0
.532 mum)\ = 2.65 +/- 0.13 pm/V, and \d33 (0.532 mum)\ = 10.7 +/- 0.5
pm/V. We establish that these coefficients have the same sign. We comp
are the obtained magnitudes with the main previously published results
