A disadvantage of the upconversion approach, however, is that the efficiency of non-linear mixing can be a strong function of the wavelengths of each of the beams and their orientation relative to the direction of the optical axis of the non-linear crystal. This phenomenon is a result of the phase-matching requirement for sum frequency generation. A detailed discussion of phase matching in fluorescence upconversion can be found elsewhere (16). [Pg.196]

Analogous to the sum-frequency generation, the parametrically generated photons o>i and cus can add up to a macroscopic wave if the phase-matching condition... [Pg.352]
