PURPOSE: To eliminate the influence of variation in the size of a spot on the operation of a device which eliminate aberrations by coupling input light beams and generating a phase conjugate reflected beam by a phase conjugation device. CONSTITUTION: This device is equipped with light source 30 which generates the input light beams, a rectangularly sectioned optical pipe 38 which has a 1st end part 38a and a 2nd end part 38b, and a light phase conjugation mirror 42; and the light source 30 guides the input light beams to the 1st end part 38a of the optical pipe 38 so that the input light beams are coupled in the optical pipe 38, which is made conjugate in phase by the coupled light-beam phase conjugation mirror 42 and guides the coupled light beams to the phase conjugation mirror 42 from the 2nd end part 38b so that the light beams are reflected by the 2nd end part 38b of the optical pipe 38 and return. |
