Abstract Get PDF(in Chinese)

2?3 μm mid-infrared lasers have important applications in medical, environmental monitoring, and military fields. The Cr∶ZnSe and Cr∶ZnS laser crystals have the advantages such as wide absorption and emission spectrum, large absorption and emission cross-sections at room temperature, and their applications in 2?3 μm mid-infrared lasers have received widespread attention. The characteristics of Cr∶ZnSe and Cr∶ZnS laser crystals and the research progress of their corresponding mid-infrared lasers are introduced, and the perspectives and future development are also proposed.
