Abstract:

The Er3+-doped crystals can produce 2.7~3.0 μm mid-infrared(MIR) lasers, which have attracted much attention for their numerous applications in laser medical surgery, optical communication, enviromental detector and electro-optical countermeasure, etc. Based on the past few years' work on the study of Er3+ activated crystals by our team, we review the effect of co-dopant rare-earth ions on the spectroscopic properties of Er3+ activated MIR laser crystals, including the sensitizing ions Cr3+, Yb3+, etc. which can enhance the intensity of characteristic absorption peaks of Er3+; the deactivating ions Ho3+, Pr3+, etc. which can inhibit the self-termination bottleneck effects, furthermore, the co-dopant Nd3+ ion can play a dual role at the same time. In the end, the expectations on the study of MIR lasers are presented.
