GVavelengths are in micrometers.

combinations can be obtained in a straightforward manner once the Sellmeier
constants are known.
ADP, KDP. and CD*A can be used to generate output at wa\yelengths in the
visible and near infrared, to about 1.1 pm or somewhat beyond. ADP and KDP
are very similar, even to the shape of the phase-matching curve (Fig. 12). CD*;A,
on the other hand, does not have enough birefringence to be pumped by a 0.355-
pm pump. However, by using a 0.532-pm pump. a parametric device tunable at
wavelengths longer than about 0.85 pm is possible (Fig. 13). 4s phase matching
can be obtained very near 90”, long nonlinear crystals may be employed without
seriously affecting efficiency through the deleterious effects of birefrin, Vence.
