Diffraction from volume reflection gratings written in bulk photorefractive lithium niobate is modeled for the case of longitudinally varying index modulation depths. Numerical solutions …
The principle of incoherent-to-coherent conversion is demonstrated in several photorefractive oxide crystals using a self-pumped phase-conjugator geometry. Resolution …
Calibrated optical Bragg‐scattering measurements of the fundamental steady‐state space‐ charge‐field amplitude, and of two higher spatial harmonics, in photorefractive p‐type …
