Full textOne challenge of today’s laser physics is the stable compression of more and more intense laser pulses to the shortest possible pulse duration to enable new high-field laser experiments and to investigate fast atomic or molecular dynamics. At present, the shortest laser pulses of the visible spectral region envelop only a few cycles of the electric field. The state of the art method to generate such short pulses behind a Ti:sapphire amplifier laser system is by means of successive steps of spectral broadening inside a gas-filled hollow fibre and dispersion compensation. However, a reliable pulse characterization is as important as the pulse compression. The more spectral bandwidth the pulse covers the more technically challenging is the measurement of the pulse’s electric field structure. In this work, new concepts of compression and characterization of pulses down to durations below 10 fs are demonstrated as well as further optimization of established techniques. Due to modern, chirped-mirror based dispersion compensation pulses as short as 3.8 fs were generated with a two-stage hollow fibre compressor. At present, these are the shortest pulses of the visible spectral region, compressed without adaptive means for dispersion compensation. For the first time the effect of self-compression of mJ-pulses to below 8 fs in a self-guiding noble gas filament is demonstrated experimentally and determined by numerical simulations. Advanced pulse characterization schemes were needed for a phase-sensitive investigation of dispersion compensation and pulse compression of white light pulses. An optimized design of the SPIDER (Spectral Phase Interferometry for Direct Electric-field Reconstruction) technique is demonstrated that facilitates the measurement of the pulse’s spectral phase in case of broadband structured spectra. With the implementation of an interferometric FROG (Frequency-Resolved Optical Gating) a new phase-sensitive pulse characterization method is introduced.

Full textThis work discusses the carrier-envelope phase drift of mode-locked lasers as well as techniques for its active and passive stabilization. In order to reveal the physical origin of the drift, the investigations focus on the analysis of residual phase noise. From the analysis, potential improvements are developed. For this purpose, in a first experimental approach, different interferometer configurations for CEP drift detection of Ti:sapphire oscillators are compared. Comparative studies clearly reveal the superiority of compact interferometer set-ups in terms of noise. In a second series of experiments, a simple assembly is introduced for the direct extraction of the phase from spectral interference patterns. The analog method is demonstrated with single-shot measurements and utilized for stabilization of the CEP drift of an amplifier system, thereby enabling monitoring of additional fast noise contributions for the first time. Moreover, a concept for orthogonal control of the CEP drift by a specially designed compensator assembly is discussed. This assembly consists of two thin wedge prisms made from different optical materials. By choosing an appropriate material group delay and its dispersion are eliminated synchronously. Furthermore, a linear method is presented that provides access to the CEP drift of ps-oscillators for the first time. The newly introduced much more general linear approach relies on resolving the spectral interference of subsequent pulses from a pulse train, which are superimposed utilizing a ring resonator. Finally, a technique is demonstrated that generates a pulse train consisting of single pulses with identical field structure. Particularly, the heterodyne signal is directly fed forward to the external feedback element, replacing the classical servo loop. Therefore, servo bandwidth limitations are eliminated. Since feedback element and laser oscillator are decoupled, the laser performance is not corrupted by side effects from the feedback.
