Glass composition and nonlinear optics glass material and nonlinear optics element for polling

摘要

The nonlinear optics effect is shown with polling, glass transition temperature is below the 570C, OH density, in mass amount ratio, is under 1000ppm above 100ppm, density of 1 value cations other than the hydrion, oxide in the mass amount ratio which is converted, is 1/10 or less of the aforementioned OH density, it makes the glass composition for polling. This glass composition be able to reveal the equal (or above equality) nonlinear optics effect to the quartz glass with polling, at the same time, it is superior in compactibility.
