Dynamic grating mediated energy transfer between two sub-picosecond pulses in LiNbO3

Two ultrashort pulses that interact in a nonlinear medium can excite a grating of the nonlinear absorption and refraction and their characteristics can be modified as a result of selfdiffraction from this grating. In this work, we adress an energy transfer between pulses of different energies and/or...

Description
Summary:Two ultrashort pulses that interact in a nonlinear medium can excite a grating of the nonlinear absorption and refraction and their characteristics can be modified as a result of selfdiffraction from this grating. In this work, we adress an energy transfer between pulses of different energies and/or different frequencies within the visible spectral range in congruent, nominally undoped LiNbO3 aiming to reveal new features that distinguish this process from the known transient and steady-state coupling of cw laser beams.
