Recent experiments demonstrated resonant excitation of single defect centers in 2D-material hexagonal Boron Nitride [1]. We present our recent results on resonant excitation of different defect centers in hBN in absence of spectral diffusion or dephasing for as long as 30 s at cryogenic temperatures (4 K). Our investigations include resonant photoluminescence excitation (PLE) of single photon emitters in a wide optical range. Furthermore, we investigated the polarization properties and phonon side band features of the defects. Together with a long coherence time [2] these properties make hexagonal Boron Nitride a promising candidate for quantum optical applications like quantum repeaters.
