Abstract

A number of aluminum-borate glasses has been developed for producing gradient index glasses by exchanging. Both positive and negative axial gradient were fabricated in the glasses by exchange of Li⁺ for Na⁺ and Na⁺ for Li⁺, respectively. Index change to 0.03 and gradient index Abble number larger than +100 were achieved. The diffusion coefficients of Na⁺ and Li⁺ in borate glasses were calculated by fitting the profiles of refractive index to complimentary error function.
