Abstract

We investigate experimentally the fundamental characteristics of space-charge waves excited in a photorefractive crystal of ${\mathrm{Bi}}_{12}{\mathrm{SiO}}_{20}.$ Features such as their transient rise and decay as well as their steady-state frequency response are investigated. Based on this, we find the dependence of the space-charge waves’ quality factor on spatial frequency and electric-field biasing. The experimental findings are compared with the linear space-charge wave theory developed previously by Sturman, et al. [J. Opt. Soc. Am. B 10, 1919 (1993) ].
