玻璃材料的制造方法和玻璃材料的制造装置
摘要：
提供能够通过无容器悬浮法制造具有优异的均质性的玻璃材料的方法。在使玻璃原料块(12)悬浮保持的状态下，通过对玻璃原料块(12)照射多个激光光线，使其加热熔化，得到熔融玻璃后，通过冷却熔融玻璃，得到玻璃材料。多个激光光线包括第一激光光线(13A)和第二激光光线(13B)。第一激光光线(13A)与第二激光光线(13B)所成的角的大小(θ)为0°以上且小于180°。第一激光光线(13A)在玻璃原料块(12)的表面上的点(S1)的中心(C1)的位置与第二激光光线(13B)在玻璃原料块(12)的表面上的点(S2)的中心(C2)的位置相互不同。
摘要（英）：

Provided is a method whereby a glass material having excellent homogeneity can be manufactured by a containerless float method. In a state in which a glass raw material lump (12) is floated and retained, the glass raw material lump (12) is irradiated with a plurality of laser beams and thereby heated and melted, and molten glass is obtained, after which a glass material is obtained by cooling the molten glass. The plurality of laser beams include a first laser beam (13A) and a second laser beam (13B). The size (theta) of the angle between the first laser beam (13A) and the second laser beam (13B) is from 0 degree to less than 180 degrees. The position of the center (C1) of a spot (S1) of the first laser beam (13A) on the surface of the glass raw material lump (12) and the position of the center (C2) of a spot (S2) of the second laser beam (13B) on the surface of the glass raw material lump (12) are mutually different.
