A Large Numerical Aperture Optical Image Amplifier Cladding Material Preparation And Performance Study

For each industry will bring great convenience because of the large numerical aperture of the optical image amplifier, so by some advanced countries focus on objects.Order to enhance the value of the numerical aperture of the fiber optic image amplifier used to reduce the refractive index of the fiber cladding glass material, which in the recipe selected, we selected the silicate glass as the basic components of the cladding material, and also introduces sesquioxide a low refractive index oxide of aluminum, hydroxide, etc. thereby to be made a silicate glass of the cladding layer of low refractive index. We used the study of the melting of the glass material, plastic, cold (coarse, fine grinding), silicate glass process can be successfully prepared by the refractive index of the cladding glass refractive index of1.50or so.
