Experimental realization of the three-way polarization-maintaining optical fiber amplifier phase-locked control to achieve the purpose of coherent synthesis output.The experimental program is introduced, and the method of phase detection and control is described in detail and a signal light is taken as an example to give the phase noise Finally, the far-field pattern of the coherent composite is given and its influential factors are simply analyzed.The experiment shows that it is feasible to increase the number of coherent composite by using the proposed scheme.
