Description
For a number of femtosecond time resolved soft X-Ray experiments, it would be a great improvement to have a femtosecond laser driven X-Ray source as a tabletop setup. In my doctorate thesis, I want to use High Harmonic Generation (HHG) to shift mid infrared laser pulses to the soft X-Ray range. To have enough power in the X-Ray range to perform absorption spectroscopy experiments, I use an infrared laser source with a power of about 30 W. This intense infrared laser light is generated by using an Optical Parametric Chirped Pulse Amplification (OPCPA) setup, which efficiently amplifies the initial laser pulses from a few nanojoule to a millijoule level. At a pulse repetition frequency of 20 kHz, the system is estimated to produce the mentioned power of 30 W of infrared laser light at the wavelength of 3500 nm. The goal is then, to use this setup to perform soft X-Ray pump-probe absorption spectroscopy experiments to analyze complex nanostructures in the time domain.
