General Topic: Plasma Induced-Hydrodynamics in gas, Plasma-Filamentation Studies, Dual-Color Plasma-based THz sources and applications

Supervisor: Dr. Malte Schröder
Starting Date: To be discussed with supervisor

List of tasks:

• Assisting with currently running experimental campaigns using a high-power ultrafast laser system (500W). Focus on laser-plasma interaction, laser filamentation application, or THz generation/detection.
• Constructing small-scale experiments/diagnostic setups for larger projects.
• Evaluation of experimental data.
• Specific tasks up for discussion.

Candidates with a background in laser or plasma physics are preferred.

Supervisor: Dr. Anna Ono
Starting date: to be discussed with supervisor

List of tasks:

• Simulating pulse compression in fiber with different parameters including input power/duration, fiber length/core size to give an instructive
• Building and optimizing the fiber-compression stage to achieve sub-10 optical cycle pulses with high overall efficiency
• Adapting current 1-µm FROG setup to 2-µm wavelength range and characterize the compressed pulse
• Further extension can be discussed depends on progress
