Phase‐matched wavelength in potassium lithium niobate (KLN) crystals grown by the micro pulling down (μ‐PD) method dependent on the atomic displacement changed by melt composition was investigated. It has been found that the polar components of the atomic displacement of the metal atoms Nb(1) and Nb(2) increase with increasing Nb content of melt. Also, phase matched wavelength for second harmonic generation (SHG) properties was determined from ultra‐violet to green region by increasing Nb content of melt.
