Priv.-Doz. Dr. Götz Alexander Lehmann
Research interests
I am working in theoretical plasma physics, with special focus on relativistic laser-plasma interaction.
Of special interest to me are
- Plasma-based photonic structures
- Amplification of short, relativistic laser pulses in plasma via stimulated Raman and Brillouin processes,
- Radiation damping in ultra-relativistic laser-plasma interaction,
- Dynamics and stability of solitary structures in laser-plasma interactions,
- Laser pulse self-compression via plasma non-linearities,
- Numerical simulations of Maxwell-Fluid and Maxwell-Vlasov models.
