ABSTRACT:
A multiple energy level, multiple pulse repetition frequency, common boresight laser energy source apparatus which employs phase conjugate energy reflection, achievable in a high-pressure gas retro-reflecting cell, to compensate for aberrations of the energy beam occurring in other optical elements. Use of the multiple energy level source in military, medical and industrial settings is described with the lowest level output energy being "eye-safe" for use by operators performing preliminary positioning and alignment of the source. The disclosure includes description of embodiment element limitations and identifications of alternate elements usable to overcome these limitations. Parallel and serial dispositions of the optical elements and discussion of advantages and limitations incurred thereby is also included.
