“…The oscillatory behaviour of the two time-dependent recording beams during the formation of the photoinduced index grating in two-wave mixing photorefractive materials has been observed experimentally in different crystals [1][2][3][4][5][6]. It is known that this behaviour is due to the temporal oscillation of the space-charge field.…”

We present our theoretical investigations into the formalism of the transient effects during photorefractive two-wave mixing. An analytical model has been developed based on Kukhtarev's band-transport equations and on the linearization approximation. The physical phenomena involved during transients have been predicted for both drift and diffusion mechanisms. Good agreement is found when our model is compared with previous works, especially with the experimental measurements performed with BSO crystals by Heaton and Solymar. †

Long-distance evolution in transient stimulated Raman scattering

Systems that exhibit stimulated Raman scattering in the transient limit have long been the subject of theoretical and experimental study, and recent experimental developments have made possible the observation of the long-distance evolution of these systems. These systems are integrable using the inverse scattering method; however, in contrast to the usual behavior in integrable systems, solitons do not dominate the long-distance behavior. Instead, solitons are transient, and self-similarity appears in the longdistance limit. In this paper, the similarity solutions of the equations which describe stimulated Raman scattering are first reviewed from a physical standpoint. Inverse scattering theory is then used to show that given physically reasonable initial data in which the pump and Stokes waves have no linear frequency mismatch, the solution will converge toward a self-similar solution. These results are confirmed by a numerical comparison of the solution of the transient, stimulated Raman-scattering equations to the appropriate self-similar solutions. The length scale over which convergence occurs and the transient generation of solitons are observed. From a physical standpoint, the appearance of self-similarity rather than solitons in the long-distance limit can be attributed to the presence of memory in the Raman-active medium. Other systems with memory also exhibit self-similarity, and the results which are described here may have applications to a wide array of optical systems with memory. An experiment which could observe self-similarity is described.PACS number(s): 42.65. Dr, 03.40.Kf, 42.50.Md prevents this approach from being applied to transient pulses, and an experimental configuration has already been proposed [12]. In this paper, we show how to calculate the evolution of transient SRS systems in the longdistance limit. At the end, we describe an experiment which could observe the predicted behavior.

“…As opposed to the spatial approach adopted in Ref. 13, we use a temporal approach based on well-known decay, 17 rise, 18 and resonance measurements 5 in time. In Section 2 the linear theory for space-charge waves in sillenite crystals is briefly reviewed, and three methods of determining the space-charge waves' quality factor are outlined.…”

Fundamental characteristics of space-charge waves in photorefractive sillenite crystals

We investigate experimentally the fundamental characteristics of space-charge waves excited in a photorefractive crystal of Bi 12 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.
