Adjacency Graphs and Long-Range Interactions of Atoms in Quasi-degenerate States: Applied Graph Theity of level crossings in systems described by irreducible matrices. In long-range interactions, the coupling parameter is the interatomic distance. We demonstrate the utility of adjacency matrices and adjacency graphs in the analysis of “hidden” symmetries of a problem; these allow us to break redu

Frequency-Comb Referenced Collinear Laser Spectroscopy of Be+ for Nuclear Structure Investigations y and frequency-comb-referenced dye lasers. Quasi-simultaneous measurements in copropagating and counterpropagating geometry were performed to become independent from acceleration voltage determinations for Doppler-shift corrections of the fast ion beam. Isotope shifts and fine-structure splittings

,Phase-Stable, Multi-μJ Femtosecond Pulses from a Repetition-Rate Tunable Ti:Sa-Oscillator-Seeded Ybfiber chirped-pulse power amplifier. A 10-nm band around 1030 nm is split from the 7-fs oscillator output and serves as the seed for subsequent amplification by 54 dB to 80 W of average power. The μJ-level output is spectrally broadened in a solid-core fiber and compressed to ~30 fs with chirped mir

Orientational Dependence of Optically Detected Magnetic Resonance Signals in Laser-Driven Atomic Matic resonance spectra for 2400 discrete orientations of . covering a . solid angle have been recorded by a PC-controlled steering and data acquisition system. Off-line fits by previously derived lineshape functions allow us to extract the relevant resonance parameters (shape, amplitude, width, and p

All Polarization-Maintaining Fiber Laser Architecture for Robust Femtosecond Pulse Generation,ing fibers. Due to a nonreciprocal phase shift, the loop mirror can be operated in a compact and efficient reflection mode, offering the possibility to reach high repetition rates and easy implementation of tuning elements. In particular, longitudinal mode spacing and carrier-envelope offset frequen

,A >2-MJ, 1014-W Laser System for DT Fusion—NIF: A Note in Celebration of the 75th Birthday of Prof.me, he and his colleagues had invented a new, high-resolution, tunable laser system using expanded reflection gratings and an N. laser for pumping the fluorescing dyes. This work resulted in a high-brightness, high-repetition-rate, narrow-band laser probe for conducting optical spectroscopy at extre
