Phase-sensitive image amplification with elliptical Gaussian pump
Michael Vasilyev, Nikolai M. Stelmakh, Prem Kumar · Optics Express · 2009
We numerically analyze phase-sensitive parametric amplification and de-amplification of a multimode field representing a multi-pixel text image. We optimize pumping configuration and demonstrate that approximately 10-dB gain is achievable with relatively moderate approximately 10- kW total pump peak power available from compact pump sources.
