| Abstract(in English) | We propose a new method to coupled a pump beam to a fiber using two mutually phase conjugate mirrors (MPPCMs). According to characteristic of MPPCM, a pump beam is coupled to a fiber as the phase conjugate beam of the beam from the fiber. Therefore, we can obtain high coupling efficiency without the processing technique and precision adjustment. The coupling efficiency in this method depends on the intensity ration of two incident beam in the photorefractive crystal. We analyze the coupling efficiency for the ratio of two pump beams, and then show the optimum ratio of two pump beams |
