Abstract The line emission peak of Eu2+ ion in crystal KMgF3 is at 360 nm. The probability of stimulated emission on 4f7(6P7/2)→4f7(8S7/2) transition was predicted with a four-level decay model of Eu2+ 6P7/2 excited states proposed by the authors. Optic gain and net gain coefficient (g=11.4±3.2)cm-1 of 360 nm emission in crystal KMgF3∶Eu2+ were measured by ASE method, and the predication was proved by experiment. The net gain coefficient can be increased by annealing or doping crystal KMgF3∶Eu2+ with Gd3+ or Ce3+.
