High-optical-depth, sub-Doppler-width absorption lines at telecom wavelengths in hot, optically driven rubidium vapor
Inna Kviatkovsky, Lucas Pache, Viola-Antonella Zeilberger +4
Doppler broadening presents a major limitation for high-resolution spectroscopy and nonlinear optics in room-temperature atomic vapors. Here, we demonstrate the suppression of Dopp…

Mid-IR hyperspectral imaging with undetected photons
Marlon Placke, Chiara Lindner, Felix Mann +5
Sensing with undetected photons has become a vibrant, application-driven research domain with a special focus on the mid-infrared (mid-IR) wavelength region. Since the mid-IR conta…
