Abstract

A process for making a custom phase-conjugated circular mirror to be used in a laser resonator that will suit specifications of a user is provided. The mirror reverses wavefront of one particular input beam ?o(x) determined by the user, the input beam ?o(x) having a given wavelength, the laser resonator including the mirror and an output coupler cooperating with the mirror and separated therefrom by a laser gain medium, the mirror being at a distance L from the output coupler. The process comprises steps of (a) determining the input beam ?o(x) that will suit need of the user; (b) calculating equation of ?L(X) which is a value of the input beam ?o(x) that is propagated through said laser gain medium at distance L; (c) calculating phase .PHI.o(x) of the input beam, which is a phase of the input beam ?o(x) at distance L, the phase .PHI.o(x) determining profile of the custom phase-conjugated mirror; and (d) fabricating the custom phase-conjugated mirror according to the profile determined in step (c), whereby a custom phase-conjugated mirror can be provided to suit the specifications of the user. There is also provided a mirror made according to the above-mentioned method.
