Degenerate four-wave mixing with a tunable excimer laser

Degenerate four-wave mixing with a tunable excimer laser Michel Versluis, Gerard Meijer, and David W Chandler We use a simple, forward-geometry degenerate four-wave mixing setup to monitor weak absorptions of various gas-phase molecules with a tunable excimer laser With this technique, state-selective detection

Squeezed-state generation via forward degenerate four-wave ,

Degenerate four-wave mixing has been suggested as a possible generation scheme for squeezed-state light A recent analysis of the quantum effects of probe-conjugate loss in backward degenerate four-wave mixing has shown that such loss puts an absolute limit on the squeezing that can be obtained via this generation scheme

Distributed analysis of nonlinear wave mixing in fiber due ,

Forward stimulated Brillouin scattering (F-SBS) is a third-order nonlinear-optical mechanism that couples between two co-propagating optical fields and a guided acoustic mode in a common medium F-SBS gives rise to nonlinear wave mixing along optical fibers, which adds up with four-wave mixing induced by the Kerr effect
