The test on its optical transmittance was conducted, and analysis of the refractive index profile of a gradient index (GRIN) rod made of the base glass was performed.

制备了自聚焦透镜的基础玻璃，对其透过率进行了测试，并对由这种玻璃制成的梯度折射率(GRIN)棒的折射率分布进行了分析。

When laser beam is incident on an inhomogeneous isotropic plasma, the variations in density profile perpendicular to main density gradient may develop, producing a rippling of critical surface.

当激光入射到非均匀的各向同性等离子体时，垂直于主密度梯度方向的密度分布会发生变化，使临界面呈现波纹。
