Taming random lasers through active spatial control of the pump
Nicolas Bachelard, Jonathan Andreasen, Sylvain Gigan +1
Active control of the pump spatial profile is proposed to exercise control over random laser emission. We demonstrate numerically the selection of any desired lasing mode from the…
Exploiting the Time-Reversal Operator for Adaptive Optics, Selective Focusing and Scattering Pattern Analysis
Sébastien Michel Popoff, Alexandre Aubry, Geoffroy Lerosey +3
We report on the experimental measurement of the backscattering matrix of a weakly scattering medium in optics, composed of a few dispersed gold nanobeads. The DORT method (Decompo…
Defocus test and defocus correction in full-field optical coherence tomography
S. Labiau, G. David, S. Gigan +1
We report experimental evidence and correction of defocus in full-field OCT of biological samples due to mismatch of the refractive index of biological tissues and water. Via a met…
