英文摘要：

Abstract TM^2＋ ： Ⅱ -VI compounds have become the most potential materials used for intrared laser due to me advantage of wide tunable range, small excited state absorption, high absorption and emission cross section and high quantum efficiency at room temperature. The research progress of TM^2＋ - Ⅱ -Ⅵ laser materials are retrospect in this paper. Both the applications of TM^2＋ ： Ⅱ -Ⅵ materials in laser devices and their preparation methods are reviewed, respectively. The laser performance of typical TM^2＋ ： Ⅱ -VI mid-infrared materials are summarized in detail, and the preparation methods for monocrystalline and polycrystalline of these materials are listed systematically. At last, the existing problems in this field are pointed out, and the development prospects and research trends are prospected.
