Multiphoton laser spectroscopy of indium monoiodide
The laser induced fluorescence (LIF) and the multiphoton ionization (MPI) spectra of indium monoiodide have been obtained at ultraviolet and visible wavelengths. Fluorescence from excited indium atoms at 451.1 nm (6s $\sp2$S$\sb{1/2}$ $\to$ 5p $\sp2$P$\sb{3/2}$) is produced by the multiphoton …

Collinear laser spectroscopy of neutron-rich niobium
… Jyväskylä. The data were taken using collinear laser spectroscopy of bunched beams. Optical pumping from the ground state to populate metastable atomic states in the ion beam cooler allowed efficient spectroscopy of the ionic system that would otherwise be inaccessible due to a lack of suitable …

Laser spectroscopy of molecular ions in an ion beam
The operation of a coaxial ion beam/laser beam experimental apparatus is described, in which an ion beam is overlapped by a laser beam and the ions are Doppler-tuned into resonance. The experimental apparatus is suitable for the study of both positive and negative ions. Resonant transitions are …

Laser spectroscopy of color centers in yttrium aluminum garnet
Nd:YAG lasers have become ubiquitous as tools for spectroscopy, materials processing, and medical care. It is well known by crystal growers that lattice defects in Nd:YAG can stifle laser efficiency, but to date very little has been done to isolate and characterize individual YAG defects. Knowing …

Diode Laser Spectroscopy for Measurements of Gas Parameters in Harsh Environments
… gases. Hence, over the last forty years, diode laser spectroscopy (DLS) has become an established method for non-intrusive measurement of gas properties in scientific as well as industrial applications. Wavelength modulation spectroscopy (WMS) is derivative form of DLS that has been increasingly …

Measurement of Time Dilation by Laser Spectroscopy on Fast Stored Lithium Ions
… Die Spektroskopie wird durch zwei gegenläufige Laser verwirklicht, die kollinear zum Ionenstrahl sind. Zwei Messungen bei zwei verschiedenen Ionengeschwindigkeiten werden durchgführt, eine Messung bei 3% Lichtgeschwindigkeit und eine bei 6,4% Lichtgeschwindigkeit. Die gemessenen …

Experimental Test of Relativistic Time Dilation by Laser Spectroscopy of Fast Ions
… of two Doppler-free techniques of collinear laser spectroscopy on a fast (v=0.064c) ion beam in a storage ring have been investigated. The first technique, Lambda-spectroscopy on a closed Lambda-type three-level system, suffered from a strong, hitherto unaccounted line broadening in a …
