Optical characterization of excited-state spin Hamiltonians and clock transitions at telecommunication wavelength in Tm3+:YAlO3
Akshay Babu Karyath, Luozhen Li, Julien Bertrand +6
The zero-phonon line (ZPL) between the two excited-state manifolds 3F4 and 3H4 of the trivalent thulium ion in yttrium aluminum perovskite (Tm3+:YAlO3) lies within the telecom E-ba…
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…
Experimental demonstration and modeling of near-infrared nonlinear third-order triple-photon generation stimulated over one mode
Julien Bertrand, Veronique Boutou, Corinne Felix +2
Triple Photon Generation (TPG) is a third-order nonlinear optical interaction in which a photon, i.e. the pump, splits into three lower energy photons, i.e. modes 1, 2 and 3. The t…
