Adiabatic manipulation of Raman process and its application to ultrashort-pulse generation techniques

Abstract

We describe the adiabatic manipulation of a Raman process in a far-off resonant three-level system and its application to nonlinear optical processes. We show that near-maximal Raman coherence is produced through the adiabatic process, enabling efficient nonlinear optical processes that are not restricted by phase matching. We also show some of recent studies in this subject that are broad Raman sideband generation covering infrared to deep-ultraviolet regions and its application to ultrashort-pulse generation based on Fourier synthesis of the Raman sidebands.
