THE REFRACTIVE INDICES AND NONLINEAR OPTICAL PROPERTY OF KIO3 CRYSTAL
KIO3晶体的折射率和非线性光学性能

The refractive indices of unpolarized KIO3 crystal in three different directions have been measured in the range of visible wavelength. The existence of type I phase matching surface in KIO3 crystal has been verified by experimental method. The optimum phase matching direc-tion in unpolarized KIO3 crystal has been found.
