The space-charge-field formation in a photorefractive crystal illuminated by a one- dimensional light pattern is studied when an alternating square-wave electric field is applied …
It is shown theoretically that the space charge field generated by two‐wave mixing in a photorefractive crystal may have a resonant response when a dc field and a sinusoidal ac …
The second order temporal differential equation, known to describe the space charge field in the high frequency region, is solved approximately in a closed analytical form. The condition …

We present the first complete theoretical model that describes the formation of the space- charge field in a photorefractive material that is exposed to a sinusoidal ac electric field with …
The spatial subharmonic instability arising from the material equations is investigated theoretically for both square and sinusoidal applied alternating electric fields. The threshold …
