“…This technique has been demonstrated by self-referencing two-wave mixing. 1 In this Letter we propose to accomplish beam cleanup by using the Brillouin effect in a multimode fiber. We demonstrate efficient and highly stable beam cleanup in a multimode gradientindex (GI) fiber by using a self-aligned loop geometry.…”

“…In this system, the incident beam intensity onto the Rh:BaTiO 3 crystal was estimated to be as much as 50 W/cm 2 . The power handling of a Rh:BaTiO 3 crystal reported previously was 1 kW/cm 2 at 1.06 mm (Lombard et al, 2004). Thus, a further improvement of the output power is possible without any damages to the Rh:BaTiO 3 crystal by refinements of the heat removal process of the amplifier.…”

An overview on current trends in stimulated Brillouin scattering and optical phase conjugation is given. This report is based on the results of the "Second International Workshop on stimulated Brillouin scattering and phase conjugation" held in Potsdam/Germany in September 2007. The properties of stimulated Brillouin scattering are presented for the compensation of phase distortions in combination with novel laser technology like ceramics materials but also for e.g., phase stabilization, beam combination, and slow light. Photorefractive nonlinear mirrors and resonant refractive index gratings are addressed as phase conjugating mirrors in addition.

Nonlinear photorefractive materials are well suited to record dynamic volume holograms using the wave mixing of coherent laser beams. The photo-induced index modulation is due to a space charge field which modulates the crystal refractive index. The basic phenomena and beam interactions are reviewed for different types of materials operating in the visible and near infrared. In particular, we outline their ability to amplify a low intensity signal beam due to the intensity transfer of a spatially multimode pump beam. We apply this interaction to the cleanup of a multimode large core fiber amplifier. This class of nonlinear materials contribute to extending the performances of laser sources for advanced applications of photonics.
