Apparatus comprising: oscillator means, disposed along a first optical path for providing coherent light at a first frequency; optics disposed along said first optical path for focusing said coherent light provided by said oscillator means; a target disposed along said first optical path at a primary focal plane of said optics; a laser amplifier disposed along a second optical path for receiving light reflected from said target and processed through a portion of said optics, which transmits, substantially unamplified, light at said first frequency and which amplifies light substantially at a second frequency; and phase conjugation means disposed along said second optical path for responding to light at said first frequency reflected from said target, and for converting light at said first frequency to light at said second frequency, and for providing phase conjugate light at said second frequency which corrects for wavefront distortions introduced into said light at said first frequency caused by said optics and said laser amplifier, said phase conjugate light being directed substantially along said second optical path in the opposite direction back through said laser amplifier for substantial amplification thereof, and through said portion of said optics to said target.
