We propose the laser cooling of bunched relativistic beams of Alkaline-like and especially all Lithium-like ions in SIS 100/300, where due to the huge Doppler-shifts (γmax=35; Bρ=300Tm) optical ground state transitions can be excited employing existing laser technology. To avoid optical pumping between hyperfine levels e-e nuclei are preferred. The principle aim is the strong improvement of the...

The crystallization of ion beams has recently been established in the rf quadrupole storage ring PALLAS (PAul Laser CooLing Acceleration System) for laser-cooled 24Mg+ ion beams at an energy of about 1 eV. Yet, unexpectedly sharp constraints had to be met concerning the confinement strength and the longitudinal laser cooling rate. In this paper, related and up to now unseen heating mechanisms a...

We review recent progress in laser cooling of fast stored ion beams at the Heidelberg Test Storage Ring, particularly concerning the development of methods to extend longitudinal laser cooling to the transverse degrees of freedom. EEcient three-dimensional cooling has been obtained on the basis of two diierent mechanisms leading to a transverse-longitudinal coupling: Storage-ring dispersion in ...

We demonstrate laser cooling of trapped beryllium ions at 313 nm using a frequency-doubled extended cavity diode laser operated at 626 nm, obtained by cooling a ridge waveguide diode laser chip to -31°C. Up to 32 mW of narrowband 626 nm laser radiation is obtained. After passage through an optical isolator and beam shaping optics, 14 mW of 626 nm power remains of which 70% is coupled into an ex...

Laser cooling of stored 24Mg ion beams recently led to the long anticipated experimental realization of Coulombordered ‘crystalline’ ion beams in the low-energy RF-quadrupole storage ring PAul Laser CooLing Acceleration System (Munich). Moreover, systematic studies revealed severe constraints on the cooling scheme and the storage ring lattice for the attainment and maintenance of the crystallin...

We report on the observation of the indirect transverse laser cooling eeect in a radio-frequency bunched beam of 7.3 MeV 9 Be + ions, stored in the Heidelberg Test Storage Ring and subject to direct longitudinal laser cooling. This bunched scheme ooers particular advantages for producing ultracold beams with unprecedented phase-space densities. The development of beam cooling techniques has eve...

We analyze two configurations for laser cooling of neutral atoms whose internal states store qubits. The atoms are trapped in an optical lattice which is placed inside a cavity. We show that the coupling of the atoms to the damped cavity mode can provide a mechanism which leads to cooling of the motion without destroying the quantum information. Cavity Assisted Nondestructive Laser Cooling of A...

Based on the assumption that the maximum irradiance allowed during laser treatment of port wine stains is limited by the temperature rise at the dermoepidermal junction, we theoretically investigated how much the irradiance could be increased by dynamically cooling the skin surface. The heat condution equation was solved numerically in cylindrical coordinates using a skin model composed of four...

By using broadband lasers, we demonstrate the possibilities for control of cold molecules formed via photoassociation. Firstly, we present a detection REMPI scheme (M. Viteau et al., Phys. Rev. A, 2009, 79, 021402) to systematically investigate the mechanisms of formation of ultracold Cs2 molecules in deeply bound levels of their electronic ground state X1sigma(g)+. This broadband detection sch...
