Characterization of an Ultrafast Optical Parametric Amplifier System

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...

Gated Frequency-Resolved Optical Imaging with an Optical Parametric Amplifier for Medical Applications

Implementation of optical imagery in a diffuse inhomogeneous medium such as biological tissue requires an understanding of photon migration and multiple scattering processes which act to randomize pathlength and degrade image quality. The nature of transmitted light from soft tissue ranges from the quasi-coherent properties of the minimally scattered component to the random incoherent light of ...

Fiber optical parametric amplifier with double-pass pump configuration.

Characteristics of fiber optical parametric amplifier (FOPA) with double-pass pump configuration are experimentally investigated. The double-pass pump FOPA exhibits more than two-fold steeper gain slope in comparison to the conventional FOPA due to elongation of effective fiber length. In the L-band amplification band, a secondary idler is generated and used as the transmission signal in lieu o...

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 ...
