TL;DR: In this article, a quasi-phase-matching (QPM) grating is used to shape the wave fronts of the output light by diffraction or phase front shaping to modify its propagation.

TL;DR: In this paper, the Sagnac interferometer was applied to magneto-optic measurements at an oblique angle of incidence, with a sensitivity of a few hundred nanoradians.

TL;DR: In this article, the authors show that the pump-to-signal power conversion efficiency of parametric chirped-pulse amplifiers made with periodically poled materials operating with multicolor spatial solitons can be significantly enhanced by employing engineered quasi-phase matching gratings.

TL;DR: In this article, an all-fiber, picosecond, Watt-level master-oscillator-power-amplifier (MOPA) system at 1.5 mum based on rapid amplification of mode-locked pulses in heavily Er:Yb codoped phosphate fiber is combined with fiber pigtailed lithium niobate intensity modulator (pulse picker), to construct a fully integrated eye-safe transmitter operating at 65-Mb/s data rate, that can be used in intermediate-range (few kilometers) atmospheric communication links.

TL;DR: In this article, a detailed investigation of the domain evolution in lithium niobate and lithium tantalate during backswitched electric field poling was presented, which allowed to produce micro- and nanoscale domain patterns by applications of voltage to lithographically defined strip electrodes.
