Label free sub-diffraction imaging using non-linear photon avalanche backlight
Suresh Karmegam, Marcin Szalkowski, Malgorzata Misiak +3
Optical imaging below the limit of light diffraction offers an unprecedented opportunity to study outlook, organization, interactions or in-situ functioning of sub-micrometer, high…

Non-invasive super-resolution imaging through scattering media using highly nonlinear labels
Pawel Szczypkowski, Adrian Makowski, Wojciech Zwoliński +5
While scattered light conveys most of the information we perceive, scattering may also distort that information before it reaches our detectors. The problem is acute in many applic…

The mechanisms behind extreme susceptibility of photon avalanche emission to quenching
Martyna Majak, Malgorzata Misiak, Artur Bednarkiewicz
The photon avalanche (PA) process that emerges in lanthanide-doped crystals yields a threshold and highly nonlinear (of the power law order > 5) optical response to photoexcitation…
