摘要:
A new scheme for high-efficiency phase conjugation of broadband laser radiation in photorefractive crystals is proposed. The scheme utilizes a dispersive ‘2–f’ system for decoupling of the photo-induced index gratings written by the different frequency components. Self-pumped phase conjugated reflectivity of 25% have been achieved over bandwidths of tens of nanometres in an undoped BaTiO3crystal using broad-spectrum Ti: sapphire laser pulses.
