We demonstrate that holographic speckle-free imaging is possible when a dynamic recording medium, such as a Bi(12)SiO(20) crystal, and a four-wave mixing configuration are used. The method is based on time integration in the conjugate-image plane of

Many industrial applications require high beam quality, compact, reliable and low cost lasers. Microchip lasers combine all these advantages. Indeed, solid state Nd:YAG microchips have the beam quality of solid state lasers. Thanks to a monolithic de

The polarization properties of the volume gratings in photorefractive B 12 SiO 20 crystals permit to increase the contrast and signal to noise ratio in the image plane of a large size vibrating object structure. The experiment is based on the nearly

We analyse in this paper the dynamic holographic recording and phase conjugation of 3-D diffuse objects in photorefractive B.S.O. crystals. Application of these concepts to mode pattern visualisation of a vibrating loudspeaker membrane is demonstrate

International audience; New configurations for spatial beam steering of a near-infrared laser beam are presented. They are based on the interaction of the beam from a semiconductor laser with a dynamic grating photoinduced in a photorefractive crysta

The high sensitivity combined with the externally controlled spatial frequency response of photoconductive electrooptic Bi12 Si 020 crystals (B.S.0.) allow real-time non destruc-tive testing either by phase conjugation in the four-wave mixing configu

We report two-beam coupling experiments at 1.06-microm wavelength using photorefractive semi-insulating GaAs:Cr in the moving-grating recording mode. The steady-state gain coefficient r is measured as a function of fringe spacing Lambda, fringe veloc
