摘要

A process for making a custom phase-conjugatedcircular mirror to be used in a laser resonator that willsuit specifications of a user is provided. The mirrorreverses wavefront of one particular input beam ?o(x)determined by the user, the input beam ?o(x) having a givenwavelength, the laser resonator including the mirror and anoutput coupler cooperating with the mirror and separatedtherefrom by a laser gain medium, the mirror being at adistance L from the output coupler. The process comprisessteps of (a) determining the input beam ?o(x) that will suitneed of the user; (b) calculating equation of ?L(X) which isa value of the input beam ?o(x) that is propagated throughsaid 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 ofthe custom phase-conjugated mirror; and (d) fabricating thecustom phase-conjugated mirror according to the profiledetermined in step (c), whereby a custom phase-conjugatedmirror can be provided to suit the specifications of theuser. There is also provided a mirror made according to theabove-mentioned method.
