Theory of beam coupling and pulse shaping of mode-locked laser pulses in a photorefractive crystal

XS Yao, V Dominic, J Feinberg - JOSA B, 1990 - opg.optica.org
We describe how optical beams from a mode-locked laser will couple in a photorefractive
crystal. We show that the two-beam-coupling gain coefficient is proportional to the square of …

Measuring the coherence length of mode‐locked laser pulses in real time

V Dominic, XS Yao, RM Pierce, J Feinberg - Applied physics letters, 1990 - pubs.aip.org
We demonstrate a new technique for displaying the electric field autocorrelation function of
11 laser pulse in real time, using two-beam coupling in 11 photorefractive crystal. This …

Slow light with degenerate backward-wave four-wave mixing

P Mathey, G Gadret, K Shcherbin - Applied Physics B, 2011 - Springer
We report on a slowing down of light pulses using degenerate backward-wave four-wave
mixing in a photorefractive crystal. The delay and width of the output pulse for the amplified …

Slow light with photorefractive four-wave mixing

P Mathey, G Gadret, K Shcherbin - Physical Review A, 2011 - APS
A slowing down of light pulses using backward-wave four-wave mixing is achieved in
photorefractive crystals with different coupling strength. The delay and width of the output …

Increase of light-beam coherence by two-wave mixing in photorefractive crystals

NV Bogodaev, LI Ivleva, AS Korshunov, NM Polozkov… - JOSA B, 1993 - opg.optica.org
We demonstrate that two-wave mixing of partially coherent light beams inside a medium with
an inertial nonlinear response allows one to increase the coherence substantially. An …

Slow light of dark pulses in a photorefractive crystal

N Bouldja, A Grabar, M Sciamanna… - Physical Review …, 2020 - APS
Slowdown of Gaussian “dark pulses” in photorefractive crystal using a two-wave mixing
method is shown at room temperature. In agreement with our theoretical model, the …

Temporal evolution of fanning in photorefractive materials

M Segev, D Engin, A Yariv, GC Valley - Optics letters, 1993 - opg.optica.org
We present detailed calculations of the temporal and spatial evolution of beam fanning in
photorefractive crystals that is initiated by scattering from noise. We show that fanning starts …

Orthogonal geometry of wave interaction in a photorefractive crystal for linear phase demodulation

S Di Girolamo, RV Romashko, YN Kulchin… - Optics …, 2010 - Elsevier
We present a novel configuration of an interferometer which is implemented by using
vectorial wave mixing in the orthogonal geometry of wave interaction in a cubic …

Two-beam cross coupling from mutually incoherent lasers

D Statman, B Liby - JOSA B, 1989 - opg.optica.org
The cross coupling of two mutually incoherent sources in photorefractive materials is
described. It is shown that when there are two mutually incoherent pump beams that are not …

Beam cleanup using photorefractive two-wave mixing

AET Chiou, P Yeh - Optics letters, 1985 - opg.optica.org
Photorefractive two-wave mixing exhibits energy transfer without phase cross talk. Such a
phenomenon can be used to clean up wave-front aberrations of laser beams. We report the …
