Coherent Modified Scattering of Light

Coherent and incoherent multiple scattering of light in seawater.

Focusing coherent light through opaque strongly scattering media.

We report focusing of coherent light through opaque scattering materials by control of the incident wavefront. The multiply scattered light forms a focus with a brightness that is up to a factor of 1000 higher than the brightness of the normal diffuse transmission.

Coherent light scattering from a two-dimensional Mott insulator.

We experimentally demonstrate coherent light scattering from an atomic Mott insulator in a two-dimensional lattice. The far-field diffraction pattern of small clouds of a few hundred atoms was imaged while simultaneously laser cooling the atoms with the probe beams. We describe the position of the diffraction peaks and the scaling of the peak parameters by a simple analytic model. In contrast t...

Coherent anti-Stokes Raman scattering imaging under ambient light.

We demonstrate an ambient light coherent anti-Stokes Raman scattering microscope that allows CARS imaging to be operated under environmental light for field use. The CARS signal is modulated at megahertz frequency and detected by a photodiode equipped with a lab-built resonant amplifier, then extracted through a lock-in amplifier. The filters in both the spectral domain and the frequency domain...

Coherent Compton scattering on light nuclei in the ∆-resonance region

Coherent Compton scattering on light nuclei in the ∆ resonance region is studied in the impulse approximation and is shown to be a sensitive probe of the in-medium properties of the ∆ resonance. The elementary amplitude on a single nucleon is calculated from the unitary K-matrix approach developed previously. Modifications of the properties of the ∆ resonance due to the nuclear medium are accou...
