Chromatic‐dispersion‐free transmission using time‐reversal optical parametric amplifier

Efficiency-enhanced soliton optical parametric amplifier

We 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. Applications include compact sources of high-energy ultrashort pulses in diffraction-limited high-quality beams. © 2002 Optical Soc...

Cascaded Nonlinear Optical Mixing in a Noncollinear Optical Parametric Amplifier

Ultrafast optical science is a rapidly evolving multidisciplinary field: the ability to excite matter with femtosecond light pulses and probe its subsequent evolution on ultrashort time scales opens up completely new fields of research in physics, chemistry, and biology.[1] Furthermore, the high intensities that can be generated using femtosecond light pulses allow us to explore new regimes of ...

Decomposing a pulsed optical parametric amplifier into independent squeezers

Abstract We discuss the concept of characteristic squeezing modes applied to a travelling-wave optical parametric amplifier pumped by an ultrashort pulse. The characteristic modes undergo decoupled single-mode squeezing transformations, and therefore they form a useful basis to describe the evolution of the entire multimode system. This provides an elegant and intuitive picture of quantum stati...

Gain smoothening filter in two-segment fiber-optical parametric amplifier

This paper demonstrates a method to remove the gain ripple profile specifically for a two-segment fiber optical parametric amplifier arising from the dispersion differences between the fiber gain medium and the standard single mode fiber attached to the optical components. This is achieved by using a simple design that incorporates a gain smoothening filter at the mid-stage of the amplifier. Th...
