０３（Ｒ’はＹ、Ｌａ。Phosphate laser glass, which contains a relatively large amount of alkaline components, has the advantage of a large stimulated emission cross section, but has poor mechanical strength and chemical durability, as well as a low coefficient of thermal expansion. The drawback is that the thermal shock resistance is low due to the large size, but the glass composition has R',

However, the combination of B'203 and R'0 has the disadvantage of reducing the stimulated emission cross section of the laser glass. On the other hand, silicate laser glasses generally have high mechanical strength and thermal shock resistance, but have a small stimulated emission cross section.

は確認した。According to the knowledge obtained by the present inventors, by replacing part or all of AI, 03 and R10, which were mixed in the glass composition with 8 x 02, in order to improve the drawbacks of conventional phosphate laser glass. ,*Without objectively damaging the stimulated emission cross-section of the phosphate laser glass (the coefficient of thermal expansion can be reduced, and therefore the thermal shock resistance can be increased), a large amount of 8i02 can be added to the phosphate glass. Although it is generally believed that this causes phase splitting or crystallization, the glass composition of the present invention not only does not exhibit such a tendency, but also provides a glass with low concentration quenching of fluorescence. The parties have confirmed.

In the range of 021i from 8 to 30%, the coefficient of thermal expansion is reduced without significantly reducing the stimulated emission cross section, but when it exceeds 30%, the stimulated emission cross section decreases from the desired value. Further, in order to reduce the coefficient of thermal expansion while maintaining the stimulated emission cross section at a high level, the total amount of P20H+S + Ot must be in the range of 65 to 95%.

である。If the total amount of L120+Na, O+ and 20 is less than 4 inches, vitrification becomes difficult, and if it exceeds 20 inches, the coefficient of thermal expansion increases, so in the present invention, a range of 4 to 20% is selected. By the way, in order to reduce the coefficient of thermal expansion, Li2
O is advantageous, but 0 is particularly advantageous in terms of increasing the stimulated emission cross section. Nd,03 is an essential component of laser glass, and in order to exhibit its properties as a laser glass, at least 0.01% of Nd2O, is required, and in the glass composition of the present invention, it is 12% (30% as Nd3+ ions).
