Projects per year
I received the Engineer Diploma in Optics from the Belarus National Technical University, Minsk, in 1999, and the Ph.D. degree from the Institute of Physics, Minsk, in 2005 for work on nonlinear effects in semiconductor quantum dots in glasses. I worked at the International Laser Centre, Minsk on nonlinear spectroscopy in quantum dots, passive mode locking and Q-switching, thermal effects in lasers from 1999 to 2007. Since 2008 I am a Research Fellow at the Institute of Photonics, where I delivered scientific objectives on two EPSRC projects (EP/E06440X/1, EP/G00014X/1), managed two strands in the ERC project (#278389) and now a Researcher-CoI in EPSRC project "Fibre-laser pumped diamond Raman lasers for LIDAR and clear plastics welding" (EP/P00041X/1).
During my career in the Institute, I undertook the first systematic study of Raman gain in diamond as a function of the pump wavelength and demonstrated the first multi-watt CW diamond Raman laser in the IR, with substantial improvement of the Raman laser beam quality over that of the pump source (brightness enhancement). I also gained experience in synthesis and spectroscopic study of colour centres in diamonds (NV and H3) for applications as laser gain material and in optical magnetometry.
Research areas and expertise:
- Solid-state lasers (VECSELs, crystalline, Raman) within spectral range of 0.6-2.5um:
Passive mode-locking (picosecond, femtosecond)
Femtosecond pump-probe for lifetime measurements
Luminescence decay kinetics
- Synthesis of colour centres in diamonds:
Electron beam irradiation
Non-linear spectroscopic effects (absorption saturation, bleaching decay)
