2.7 ~ 3μm mid-infrared laser has important application prospect in spectrum analysis, gas detection, laser medical treatment and optical parametric oscillation pump. Recently, with the support of the National Natural Science Foundation of China, Sun Dunlu, a researcher from the Laser Center of An Guang, made a series of new progresses in the exploration of highly effective radiation-resistant 2.7-3 μm mid-infrared laser crystals. The research achievements have been published in American Optical Society (OSA) Journal OL, OE.
In the study of the anti-radiation properties of laser crystals, the researchers used 60Co γ-ray source,
In the aspect of enhancing the laser efficiency of mid-infrared crystal and the laser performance under high repetition rate, they were studied by incorporating deactivated ions such as Pr3 + and Ho3 + and sensitized ions such as Yb3 + and Cr3 +
In addition, the research group in recent years has been committed to crystal thermal bonding technology and related performance studies. At GYSGG / Er,
The related work has been funded by the National Natural Science Foundation of China and major research project nurturing projects.
