3-5?m mid-infrared wave band is in the atmosphere window, which has lots of promising applications on the spectroscopy, remote sensing, medical treatment, environmental protection and military affairs. So, it has been a hot topic around the world to research the lasers at this wave band. In this paper, we describe three ways to get the mid-infrared lasers: technology based on nonlinear theory, quantum cascade technology and doping ions in crystal technology. At last, we point out the trends of their developments respectively.
