Abstract
Two-dimensional image transfer with frequency upconversion from the pump to the anti-Stokes beam has been realized using polarization coupling in rotational Raman scattering. With two pump beams of counter-rotating circular polarization from a Q-switched Nd:YAG laser, images carried in either pump can be transferred to the anti-Stokes beam through pump-phonon coupling in a hydrogen cell. Image addition has also been demonstrated when different objects are inserted simultaneously in two pump beams. The potential for imaging through scattering media with this technique is discussed.
