ABSTRACT:
A coherent energy transfer system is disclosed which utilizes a doublet pulse laser transmitter in combination with a phase conjugate mirror (PCM) assembly. In one embodiment of the present invention, the first pulse of the doublet pulse signal illuminates the target, whereas the return pulse reflected from the target constitutes a weak signal to be processed using phase conjugate methods. The second pulse of the doublet phase signal activates the PCM assembly and constitutes the energy source used to produce an amplified, phase conjugated beam.
