Dr Fedosejevs' past research and development work includes the development and application of picosecond optical probe techniques to the study of high power laser-plasma interactions and high temperature plasma phenomena. He has been a visiting scientist at the National Research Council of Canada, the Max-Planck-Institute fuer Quantenoptik in Germany, CELIA (Centre Laser Intenses et Applications) at Bordeaux and at the Institute for Laser Engineering at Osaka University in Japan. He has worked on a number of laser systems including high power nanosecond carbon-dioxide, iodine and glass lasers, picosecond glass and krypton fluoride lasers, and femtosecond krypton fluoride and Ti:Sapphire laser systems. With these systems he has studied a number of high temperature plasma phenomena including absorption, plasma instabilities, x-ray generation, hydrodynamics of the laser produced plasmas and applications in micromachining, laser sensing and laser deposition of thin film coatings. Many of the studies have been related to the quest to develop laser fusion energy.
Dr Fedosejevs has published over 200 research papers.
Dr Fedosejevs' current research interests include:
- Application of lasers in material identification sensor applications using techniques such as laser induced breakdown spectroscopy, Raman spectroscopy and laser induced fluorescence.
- Devlopment of high power pulsed fibre and solid state lasers.
- Laser Fusion Energy and Fast Ignition.
- Wakefield acceleration of MeV electrons.
- Laser plasma interactions on femtosecond and picosecond time scales, including: absorption of laser light, multiphoton ionization and hydrodynamics.
- Femtosecond generation of x-rays and applications to time resolved x-ray microsocpy.
- Femtosecond laser micromachining.
- Development of a high energy proton telescope for applications in space and laser plasma research.
