New frontiers of ultrafast thin-disk laser oscillators for applications in metrology and the generation of THz and XUV radiation

Modsching, Norbert Paul ; Südmeyer, Thomas (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Ultrafast laser systems find application as versatile tool in industry and science. Ultrafast laser systems based on Ti:sapphire – the workhorse in ultrafast science – operate typically at kHz repetition rates and benefit from the available broad gain bandwidth for the direct generation of sub 100-fs pulse durations. However, thermal effects in the gain medium due to a high quantum defect...

Novel ultrafast high-power thin-disk laser oscillators and applications for metrology and XUV generation

Paradis, Clément ; Südmeyer, Thomas (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Ultrafast lasers have revolutionized research in fundamental physics, chemistry and biology as well as industrial applications. A great number of experiments benefit from the development of Yb-based high-power femtosecond laser sources. These systems typically include a low-power mode-locked oscillator followed by amplifier stages relying on fiber, slab or thin-disk technologies. In many cases,...
