Phase-Locked Detection of Running Interference Pattern in Photorefractive SBN

Phase-Locked Detection of Running Interference Pattern in Photorefractive SBN

Holographic grating in a photorefractive crystal may be recorded due to the diffusion of electrons or their drift in external or Intrinsic photovoltaic dc field as a result of illumination by a static interference pattern. Those traditional mechanisms are well studied. Running interference pattern m...

Zusammenfassung:Holographic grating in a photorefractive crystal may be recorded due to the diffusion of electrons or their drift in external or Intrinsic photovoltaic dc field as a result of illumination by a static interference pattern. Those traditional mechanisms are well studied. Running interference pattern may be registered by the phase-locked detection in the externally applied ac field. That mechanism was realized in the paraelectric crystal Bi12TiO20 (BTO). In this work we have performed the phase-locked detection mechanism in the ferroelectric photorefractive crystal SBN:Ce.
