The project consists in adapting the successful ultrashort pulse characterization technique d-scan to a new wavelength regime, the mid infrared wavelength range. This project includes a lot of interesting optics, second harmonic generation, ultrashort laser pulses, with hands on experience on a modern laser system.
Understanding the "rings" in high-order harmonic generation
The project consists in learning to use a newly-developed MATLAB code for the propagation of high-order harmonic generation in gases, with aim to understand the apparition of rings in space and frequency spectrum. This project is mostly about simulations but could include participating to experiments as well.
Optimizing high-order harmonic generation around 50 eV
Interesting applications in atomic or molecular physics require strong XUV radiation in the 40-50 eV range. This project consists in generating high order harmonics in atomic and molecular gases and to optimize the radiation strength in the 40-50 eV range.
Measuring the wavefront of XUV radiation
This project consists in assembling and testing an instrument for the measurement of the wavefront of XUV radiation. At the same time, a nonlinear signal will be recorded. One aim is to correlate the strength of the signal with the spatial characteristics of the radiation.
