Radiative lifetimes of 79 levels belonging to the 3d34s4p, 3d44p, 3d34s5p, 3d45p, and 3d34s4d configurations of V i with energy from 26,604.807 to 46,862.786 cm−1 have been measured using time-resolved laser-induced fluorescence (TR-LIF) spectroscopy in laser-produced plasma. The lifetime values reported in this paper are in the range of 3.3–494 ns, and the uncertainties of these measurements a...

If atom lasers are to transform many fields of physics, as well as find applications in industry, the most essential development needed is increased atom flux. In this thesis we report on the experimental observation of fundamental limits on the flux of continuous atom lasers. The flux produced by the commonly used radio frequency outcoupler, can not be arbitrarily increased by increasing the s...

Xe2+ ions can easily be formed by multiphoton absorption in Xe atoms at 0.53 03BCm. At low laser intensities, a laser-Xe atom interaction takes place which generates Xe2+ ions through a 15-photon absorption from Xe atoms. At higher intensities, a laser-Xe+ ion interaction takes place, generating Xe2+ ions through a 10-photon absorption from the Xe+ ion in its ground state. The former process is...

We investigate nonclassical properties of the output of a Bose-Einstein condensate in Milburn’s model of intrinsic decoherence. It is shown that the squeezing property of the atom laser is suppressed due to decoherence. Nevertheless, if some very special conditions were satisfied, the squeezing properties of atom laser could be robust against the decoherence. PACS numbers: 03.75.Gg, 03.75.Pp, 0...

An all-solid-state 252 nm coherent light source with external cavities for laser cooling silicon atoms using twostage highly efficient frequency conversions has been developed. With the coherent light source, it is possible to manipulate the atomic motion of the silicon atoms, which is necessary for nano-process applications. In this paper, deflection, collimation, and axial velocity selection ...

By direct comparison between experiment and theory with no adjustable parameters, we show how the classical fluctuations on a multistate atom laser beam increase with increasing flux. The fluctuations are inherent to state changing out coupling, rf, Raman, or otherwise and are likely to be present in all atom lasers, pulsed or continuous, that employ such out coupling. If not removed or avoided...

This thesis aims at extending the capabilities of ultrafast science in manipulating light fields. The instantaneous field of light transients has been tailored on demand with attosecond resolution by implementing ultrawideband field synthesis in the visible and flanking ranges. First experiments utilizing the considerably improved resolution, such as the study of ionization dynamics of the Kr a...

In the cation of the title compound, [Ag(4)(C(2)F(3)O(2))(2)(C(12)H(10)O(2)P)(2)(C(25)H(22)P(2))(2)]·2CH(3)CN, the two independent Ag(+) cations are four-coordinated in a distorted tetra-hedral geometry by one P atom from a bis-(diphenyl-phosphan-yl)methane (dppm) ligand, one O atom from a trifluoro-acetate anion and two O atoms from two diphenyl-phosphinate (dpp) ligands. Two dppm ligands, two...

The development of the Raman atom laser promises to make available new techniques for accessing and manipulating the quantum statistical properties of Bose-Einstein condensates. In this work we show how, combined with the already existing methods for the manipulation of quantum states of light which are central to quantum optics, the Raman input-output coupling mechanisms potentially enable the...

Recent advances in high-intensity laser-produced plasmas have demonstrated their potential as compact charge particle accelerators. Unlike conventional accelerators, transient quasi-static charge separation acceleration fields in laser produced plasmas are highly localized and orders of magnitude larger. Manipulating these ion accelerators, to covert the fast ions to neutral atoms with little c...
