Gk. Kitaeva et al., VISIBLE AND INFRARED DISPERSION OF THE REFRACTIVE-INDEXES IN PERIODICALLY POLED AND SINGLE-DOMAIN ND-MG-LINBO3 CRYSTALS, Applied physics. B, Lasers and optics, 66(2), 1998, pp. 201-205
Dispersion characteristics of bulk single-domain and periodically pole
d Nd:Mg:LiNbO3 crystals are measured in the transparency region (with
the accuracy +/-0.0002) and for the upper phonon polariton branch (wit
h the accuracy +/-0.003-+/-0.05), from 0.44 mu m up to 10.5 mu m. The
method of spontaneous parametric light scattering is used for measurem
ent of the ordinary refractive index dispersion in the mid-infrared re
gion and for determination of the domain grating period d=5.6+/-0.2 mu
m in the periodically-poled crystal.
