Stabilization techniques and silicon-germanium saturable absorbers for high repetition rate mode-locked lasers
… integration of passively mode-locked solid-state lasers at highest repetition rates has been prevented by Q-switching instabilities and the lack of integrable saturable absorbers to date. In this thesis we demonstrate in theory and experiment that active feedback electronics controlling the …

Isotope shift spectroscopy of ions in cryogenically cooled neutral plasmas
… to produce cold and dense neutral plasmas by laser ablation of metal targets, followed by cryogenic buffer gas cooling. In this ion source, large ion densities (≤ 109 cm-3) can be obtained at temperatures as low as 6 K. The lasers used for the isotope shift measurements were stabilized using a …

A stabilized master laser system for differential absorption LIDAR.
… and precise wavelength control of master diode lasers. This stabilization system design has a number of novel elements that work towards a robust and low-cost autonomous DIAL observatory. With two continuous wave optical wavelengths stabilized, a pulse is formed using an Acousto-Optic Modulator …

Coherent Processes in Rare-Earth-Ion-Doped Solids
… to carry out the phase-sensitive experiments, a laser system with a very narrow linewidth of ~1 kHz at 606 nm was constructed, by locking the laser to a semi-persistent spectral hole. In addition, many experiments required advanced pulse shapes, such as complex sechyp pulses or pulses obtained …

Quantum computing with naturally trapped sub-nanometre-spaced ions
… still be addressed separately by using different laser frequencies. Since the inter-ion spacing is so small, it is possible to make two ions interact strongly, although they are well shielded, through a permanent dipole-dipole interaction. This interaction can be turned on and off by switching …
