These advantages make DF laser attractive to researchers in the mid-infrared laser field. In order to effectively improve the output performance of non-chain DF lasers, the key technologies of DF lasers were researched in this paper. The key technologies including self-initiated volume discharge, mixture ratio and recirculating and cooling were introduced. Particular emphasis was put on self-initiated volume discharge. These technologies will provide theoretical guidances for the further research on DF lasers.
