Extensive ab initio study of the valence and low-lying Rydberg states of BBr including spin-orbit coupling J. Chem. Phys. 124, 194307 (2006) We present for the first time a coherent ab initio study of 39 states of valence, Rydberg, and ionpair character of the diatomic interhalogen ICl species through large scale multireference variational methods including spin-orbit effects coupled with quantitative basis sets. Various avoided crossings are responsible for a non-adiabatic behaviour creating a wonderful vista for its theoretical description. Our molecular constants are compared with all available experimental data with the aim to assist experimentalists especially in the high energy regime of up to ∼95 000 cm −1 .

“…Ifthe pumping radiation is Gaussian in profile, has a pulse length of T= 10 -6 and does not saturate the excitation transitions, then we obtain a brightness value of B =1.94 x 1O7W mm3 s ', satisfying the condition in Eq. (12). However, note that the exact parameter values for mercury vapor depend somewhat on the amount of quenching gases (e.g.…”

“…As this work was never meant to lead to a 3D display -photochemical applications had been standing in the center of interest-the used wavelength were mainly in the visible area (between 410 nm and 800 nm). 9 In 1989, Kim et al realized a volumetric 3D display based on two-step upconversion in rubidium vapor. Two low power diode laser beams (one red laser at 630 nm and one near-IR laser at 780 nm) intersect orthogonally in an enclosure containing the rubidium vapor.…”

The two basic classes of volumetric displays are swept volume techniques and static volume techniques. During several years of investigations on swept volume displays within the FELIX 3D Project we learned about some significant disadvantages of rotating screens, one of them being the presence of hidden zones, and therefore started investigations on static volume displays two years ago with a new group of high school students. Systems which are able to create a space-filling imagery without any moving parts are classified as static volume displays. A static setup e.g. a transparent crystal describes the complete volume of the display and is doped with optically active ions of rare earths. These ions are excited in two steps by two intersecting IR-laser beams with different wavelengths (two-frequency, two-step upconversion) and afterwards emit visible photons. Suitable host materials are crystals, various special glasses and in future even polymers. The advantage of this approach is that there are only very little hidden zones which leads to a larger field of view and a larger viewing zone, the main disadvantage is the small size of the currently used fluoride crystals. Recently we started working with yttrium-lithium-fluoride (YLiF 4 ) crystals, which are still very small but offer bright voxels with less laserpower than necessary in CaF 2 crystals. Potential applications are for example in medical imaging, entertainment and computer aided design.

Two-step excitation of fluorescence in iodine monochloride vapor

Abstract: Two-step sequential excitation of fluorescence was produced in ICl vapor using two synchronized tunable laser sources. The pumping scheme involved the E←A←X electronic transitions with subsequent E→A transitions being observed in fluorescence.
