This paper introduces the basic concept and application of the debugging-free laser and summarizes the new research progress on the research of the debugging-free laser at home and abroad in the aspects of realizing small and light weight laser, multiwavelength output, improving the beam quality of large energy / high power laser, New trend of research on application of pyramidal prism resonator. The recent progress in the field of coherent synthesis of pyramidal prism resonators has been reported in detail, and the coherent synthesis of pyramidal fiber lasers and the co-synthesis of pyramidal solid-state lasers based on mutual injection have been realized respectively. In order to achieve high reliability, high energy, high power and high Beam quality laser output provides an effective technical approach.
