This thesis describe the developement of a high-repetion rate time- and angle-resolved photoemission experimental setup. First, the work describes the light source developed for the experiment, based on ultrafast Ytterbium lasers and optical paramentric chirped pulse amplification. In the second part the light source is frequency upconverted to the extreme-ultravioled using the process high-harmonic generation. Finally, the experimental setup is described and applied to studies of ultrafast carrier dynamics in the 2D semiconductor tungsten diselenide.
