Abstract
Homogeneity of potassium lithium niobate single-crystal fibers grown b y micro-pulling-down technique is examined via second-harmonic-generat ion measurement both in axial and radial directions, It is found that fluctuation of phase-matching wavelength along the growth axis is smal l and independent of growth rate. On the other hand, relatively large variation of phase-matching wavelength is found along the radial direc tion. The phase-matching wavelength shows its minimum around the cente r of the section of the fiber and increase toward the periphery. Compo sitional inhomogeneity and internal strain in the radial direction are investigated in association with variation of phase-matching waveleng th. X-ray rocking-curve analysis, absorption measurement and polarized beam transmittance are also reported.
