Abstract
Coherent transfer of laser energy between laser fields with high efficiency (85-95%) is obtained by energy coupling of nearly copropagating (intersecting) laser beams in mono-atomic vapor and provides an output beam of high power when nearly equal energy pulses are tuned near resonance with the transition of the atom of the vapor (e.g., potassium vapor at 230.degree.-260.degree. C.). The frequencies of the beams differ by approximately the inverse of the excited state lifetime of the atoms for optimum combining (coupling efficiency).
