Abstract

We investigate the tracking ability of an optical phase conjugator using a commercial CCD array and a projector LCD panel. This system allows one to use two separate laser oscillators for capturing interference patterns and generating phase conjugate light. Since a long coherence length is not required for the latter part, amplification of the phase conjugate light can be easily attained by using a laser oscillator for high-power applications such as machining. The wavelengths of the two laser oscillators can be independently chosen. For our experimental configuration an amplification factor of 7.8×104 is theoretically possible. Also, a formula for the maximum tracking range is derived. The proposed system is particularly suitable for power transmission by light.
