Aim To study the laws of laser gain varying with the electric field. Methods Gain coefficient in the case of Doppler broadening is simpled; Using gain coefficient to derive the dynamic equations of laser systems. Results A dynamic equations was obtained,in which gain coefficient varys with the electric field in laser system;the curves of the gain changing with the field were given. Conclusion Gain coefficient changes not only with the frequency but also with the electric field. The curve of gain coefficient changing with the field is similar to horizontal projectile motion curve.
