Photon upconversion through high harmonic generation, multiphoton absorption, Auger recombination and phonon scattering performs a vital role in energy conversion and renormalization. Excitons, the ...

The new approach uses a purely optical technique called stimulated two-photon excitation to generate streams of photons in different polarization states directly from a quantum dot without requiring ...

The Ultima 2Pplus All-Optical Multiphoton System combines high resolution, deep imaging capability, speed, and operational flexibility, enabling researchers to efficiently perform simultaneous imaging ...

Assistant Professor of Biomedical Engineering Yi Xue works on 2P-FOCUS, a new two-photon microscopy system, in her lab. The system promises novel insights into biological features that were once only ...
