title: Continuous-wave backward-wave generation by degenerate four-wave mixing in ruby.
abstract: This is the first reported demonstration of cw wavefront conjugation by degenerate four-wave mixing in a solid. Conversion efficiencies of 3% for conjugate-wave generation were obtained in a ruby crystal using a cw argon-ion laser.
