Spectroscopy and Coherence of an Excited-State Transition in Tm:YAlO at Telecommunication Wavelength
Luozhen Li, Akshay Babu Karyath, Julien Bertrand +12
We characterize spectroscopic and coherence properties of the 1451.37 nm excited-state zero-phonon line (ZPL) between the and the manifolds of a thulium-dop…
