Research interests

1. Basic processes and spectroscopic characterization of doped laser materials (crystals, ceramics) by high-resolution absorption, emission and excitation spectra and emission dynamics: energy levels, transition probabilities, interaction with the crystal field, electron-phonon non-resonant and resonant processes, ion-ion interaction and energy transfer.

2. Quantum electronics processes in doped transparent materials:
    - Energy transfer sensitization processes;
    - Saturable absorption;
    - Upconversion of excitation by multiple absorption and energy transfer (ion-ion,
      cooperative) processes;
    - Down-conversion quantum cutting processes.
