Sergio Vincenzo Marchese

Towards High Field Physics with High
Power Thin Disk Laser Oscillators

1st edition 2008. XXIV, 126 pages; € 64,00. ISBN 3-86628-193-5


The thesis describes the development of high power passively mode-locked thin disk laser oscillators and investigates their potential to drive high field physics experiments at megahertz repetition rates. Many experiments benefit significantly from such repetition rates, which are three to four orders of magnitude higher than those from kilohertz laser amplifier systems typically used in this field: measurement times can be reduced and the improved signal-to-noise ratios result in high quality measurements even at low laser intensities. Moreover, ultrashort laser pulses improve the precision and quality of material processing applications, and the high repetition rates bear considerable potential for unprecedented processing speeds.

Among the results presented in this thesis is a Yb:YAG thin disk laser oscillator that generates 11-μJ pulses with a duration of 800 fs at a repetition rate of 4 MHz. This pulse energy is unprecedented in laser oscillators with no external amplification. Also presented is a Yb:Lu2O3 thin disk laser that delivers considerably shorter pulses with a duration of 370-fs at efficiencies that have previously not been obtained with passively mode-locked thin disk lasers. Finally, the first high field physics experiments driven by a thin disk laser oscillator are presented: photoelectron imaging spectroscopy (PEIS) of xenon is performed for the first time at multi-megahertz repetition rates using the temporally compressed output pulses of a thin disk laser. Intensities of up to 6·1013 W/cm2 are obtained, which demonstrates the suitability of the laser source for high harmonic generation.
