Abstract

The invention is a novel doped rare earth ion Nd 3+ Transparent vanadate glass series: V 2 o 5 -SiO 2 -MO(CaO+BaO+SrO)-X 2 O(Na 2 O+K 2 O+Cs 2 O)-Nd 2 o 3 . Doped with Nd 3+ Compared with this type of glass, various types of substrates have the highest gain coefficient and good optical properties, and are excellent candidates for laser beam amplification. It is expected that the ultra-strong laser system in high-energy nuclear fusion simulation experiments will achieve its physical indicators and reduce system costs. , Improve system efficiency.

Description

technical field [0001] The present invention relates to a class of novel laser beam amplification materials (especially fiber laser materials), in particular, the present invention relates to a class of doped rare earth ion Nd 3+ The transparent vanadate glass, which has a high gain coefficient and good optical properties, is expected to achieve its physical indicators, reduce system costs, and improve system efficiency in super-intensive laser systems for high-energy nuclear fusion simulation experiments. technical background [0002] The super-powerful laser system of the high-energy nuclear fusion simulation experiment is not only the hope of new energy for human beings in the future, but also plays an extremely important role in national defense. Especially today when nuclear experiments are completely banned in the world, without the super-powerful laser system of high-energy nuclear fusion simulation experiment, it is impossible to guarantee and continue the national d...
