The method of chaotic controlling is presented via controlling the phase in He-Ne lasers under optical feedback, which is based on the analysis of the chaotic dynamics characteristics of He-Ne lasers in the feedback light. The dynamics equations and physical model under the control of laser chaotic feedback phase cycle are established. Selecting appropriate feedback coefficient, the laser chaos can be controlled to a steady state, periodic state, and chaos state by controlling the feedback coefficient and the phase-shift of the feedback light using the phase controller in the feedback channel. Under the conditions of different intensities of feedback light, it is shown that, after a certain time of relaxation, chaos can be controlled into periodic state, dual periodic state, triple periodic state and multiple periodic state respectively by 1/8, 1/4, 1/2 and one wavelength periodic phase-shift modulation.
