For a deeper understanding of the outstanding real-time photorefractive medium LiNbO:(Bi,Mg) and excitonic processes in general, stoichiometric LiNbO (SLN) crystals are investigated using low-intensity near-ultraviolet (UV) irradiation and infrared-ultraviolet absorption spectroscopy. Absorption bands separated in SLN:Bi and SLN:(Bi,Mg) are assigned to specific Bi defect types and their persistent association with self-trapped excitons (pinned STEs, PSTEs) generated by near-UV irradiation. Processes on widely differing timescales are predicted for one- and two-photon excitations involving different excited states, relevant for further optimization of the system.

High-spin systems with reduced crystal symmetry reveal strongly anisotropic magnetic resonance. Identification of defect-related species requires us to disentangle effects such as anisotropic Zeeman or zero-field splitting, which can be very challenging using traditional magnetic resonance. Here, the authors propose and demonstrate a new cavity-free method for measuring electron paramagnetic resonance at high magnetic fields using frequency-tunable terahertz ellipsometry. Spin Hamiltonian parameters are obtained for the iron defect in monoclinic GaO, and compared with results from advanced theory calculations.
