.Refractive indices and the lariation of the refractive indices with temperature evaluated at 1.064 pin
esczpt for T?&, which is evaluated at 2.1 pm. Thermal conductivities are quoted for the different
crytallopaphic directions where available. In some cases, only a single value for the thermal con-
ductivity was available.

information, the effective nonlinear coefficient can be obtained by decomposing
the interacting electric field vectors into the coordinate system of the nonlinear
crystal and performing the matrix multiplication indicated in the previous sec-
tions. However, this has already been done and the effective nonlinear coefficient
