STED imaging of green fluorescent nanodiamonds containing nitrogen-vacancy-nitrogen centers

Demetri Psaltis, Grégoire Pierre Jean Laporte

We report Stimulated Emission Depletion (STED) imaging of green fluorescent nanodiamonds containing Nitrogen-Vacancy-Nitrogen (NVN) centers with a resolution of 70 nm using a commercial microscope. Nanodiamonds have been demonstrated to have the potential ...

Nanoscopy in nonlinear scanning fluorescence imaging systems

Grégoire Pierre Jean Laporte

In the last 30 years, superresolution in optical microscopy has been a major field of research. During this time, different techniques have been created to break the diffraction limit in order to make observations at a nanometric scale. Given that optical ...

Enhanced resolution in a multimode fiber imaging system

Demetri Psaltis, Christophe Moser, Grégoire Pierre Jean Laporte, Nicolino Stasio

Multimode fibers have recently been demonstrated to be a promising candidate for ultrathin and high resolution endoscopy. However, this method does not offer depth discrimination for fluorescence imaging and the numerical aperture of the fiber limits its r ...

Double-helix enhanced axial localization in STED nanoscopy

Demetri Psaltis, Andreas Vasdekis, Grégoire Pierre Jean Laporte, Donald Benjaman Conkey

Stimulated Emission Depletion (STED) microscopy enables subdiffraction resolution in the imaging plane. However, STED's lateral improvement in resolution is generally better than the enhancement in the axial direction. Here, we combine conventional STED su ...

Imaging through turbid layers by scanning the phase conjugated second harmonic radiation from a nanoparticle

Rachel Grange, Demetri Psaltis, Chia-Lung Hsieh, Ye Pu, Grégoire Pierre Jean Laporte, Ye Pu

We demonstrate imaging through a turbid layer by using digital phase conjugation of the second harmonic field radiated from a beacon nanoparticle. We show that the phase-conjugated focus can be displaced from its initial position by illuminating the same r ...
