本文探讨了二价、三价、四价和五价铬离子掺杂的一些激光晶体的光谱特性，由于分属于d4、d3、d2、d1电子组态，在不同配位体和晶体场场强变化时，其特征光谱显示了不同的变化，因而在脉冲激光，可调谐激光，激光调Q和锁模技术中发挥着不同的作用。In this paper, the optical characteristics of Cr-ion-doped crystals are introduced. The absorption and emission spectra of Cr2+(d4), Cr3+(d3), Cr4+(d2) and Cr5+(d1) ions show its properties varied with symmetry and crystal field. There application in new wavelength laser, tunable laser, high power pulse laser, Q-switched technology and mode-locked laser is presented.
