TITLE WAVELENGTH CONVERSION BY QUASI PHASE MATCHING AND THE MANUFACTURE AND USE OF OPTICAL ARTICLES THEREFOR ABSTRACT OF THE DISCLOSURE Articles and process for wavelength conversion are disclosed which use a series of aligned sections of optical materials for wavelength conversion selected from materials having the formula K1-xRbxTiOMO4 where x is from 0 to 1 and M is selected from P and As and materials of said formula wherein the cations of said formula have been partially replaced by at least one of Rb+, Tl+ and Cs+, and it least one of Ba++, Sr++ and Ca++. The series of sections is characterized with regard to a change in nonlinear optical coefficient, section length, and section .DELTA.k (i.e. the difference between the sum of the propagation constants for the incident waves and the sum of the propagation constants for the waves generated). The sections are selected such that the sum for the series of the product of the length of each section with the .DELTA.k is equal to about 2.pi.N (where N is an integer other than zero) and the nonlinear optical coefficient for at least one section is changed relative to the nonlinear optical coefficient for at least one adjacent section. Also disclosed is a process for preparing a channel waveguide for wavelength conversion systems wherein areas along a portion of a crystal substrate surface used for forming the desired channel are alternately masked and unmasked during cation replacement by immersion in a molten salt.
