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…

Semi-classical modelling of second-order spontaneous down-conversion measured over 10 decades of pump intensity in a type II phase-matched KTP crystal
Julien Bertrand, Véronique Boutou, Benoît Boulanger
We performed a second-order spontaneous parametric down-conversion (SPDC) experiment in a Type II phase-matched KTiOPO4 crystal pumped at 532 nm giving birth to a signal beam at 10…
