Large, single domain crystals of KTA and RTA are now commercially available for nonlinear optical and electrooptic device applications.  Development of CTA is in progress and crystals are available on a R&D basis. These materials feature large nonlinear optical and electrooptic coefficients, and have significantly reduced absorption in the 3-5 mm region as compared to KTP. The large nonlinear coefficients are combined with broad angular and temperature bandwidths. Additional advantages of the arsenates are low dielectric constants, low loss tangent and ionic conductivities orders of magnitude less than KTP. Single crystals of these arsenates are chemically and thermally stable, nonhygroscopic and highly resistant to high intensity laser radiation.
