Optofluidic jet waveguide for laser-induced fluorescence spectroscopy
Optics Letters, 2012An optofluidic water-jet waveguide on chip for fluorescence analysis is presented. A high-speed water stream produced by means of a microchannel acts at the same time as the solution to analyze and as the collecting optical waveguide. The absence of solid walls and the very optically smooth surface of the liquid stream permits a strong increase of the ...

Saturation effects in laser induced fluorescence spectroscopy
Applied Optics, 1977Laser based spectroscopic diagnostic tools offer the possibility of spatially and temporally resolved measurements of species concentrations in complex reacting gas flows of engineering interest. The major problem associated with such measurements is the effect of quenching reactions on the fluorescence signal.

Laser induced fluorescence attenuation spectroscopy: detection of hypoxia
IEEE Transactions on Biomedical Engineering, 2000The development of a new laser-induced fluorescence (LIF) spectroscopy technique for the measurement of the attenuation spectrum of tissue is described. The technique, termed laser-induced fluorescence attenuation spectroscopy (LIFAS), has been applied to study the effects of hypoxia on the in vivo optical properties of renal and myocardial tissue in ...

The laser-induced fluorescence spectroscopy of CoF in the ultra violet region
Journal of Molecular Spectroscopy, 2007Abstract The laser-induced fluorescence (LIF) spectrum of jet-cooled 48 TiF has been obtained in the wavelength region of 245–270 nm for the first time. Six pairs of vibronic bands were observed and assigned to two new transitions [37.8] 4 Φ-X 4 Φ and 4 Δ-X 4 Φ.

Laser Induced Fluorescence Spectroscopy of the Hydroxyl Radical
Spectroscopy Letters, 1992Abstract The hydroxyl radical has been generated by the excimer laser photolysis of nitrous acid at 248 nm. Rotationally-resolved excitation spectra in the wavenumber range 32170–32745 cm−1 of the hydroxyl (OH) radical obtained by the Laser Induced Fluorescence (LIF) technique have been assigned.

Laser induced fluorescence spectroscopy of ruthenium monoboride
Chemical Physics Letters, 2012Abstract Laser induced fluorescence spectrum of ruthenium monoboride (RuB) in the visible region between 500 and 575 nm was studied. RuB molecule was produced by reacting laser ablated ruthenium atom with 0.5% diborane (B 2 H 6 ) seeded in argon. Three transition bands of the [18.4]2.5–X 2 Δ 5/2 transition were recorded and rotationally analyzed ...

The laser-induced fluorescence spectroscopy of yttrium monosulfide
Journal of Molecular Spectroscopy, 2015Abstract We have investigated the laser-induced fluorescence (LIF) excitation spectra and dispersed fluorescence (DF) spectra of yttrium monosulfide (YS) in the energy range of 17 860–20 700 cm −1 . Rotational analyses indicated that almost all of the intense vibronic bands can be attributed to the new [ 19.38 ] 2 Σ + ( υ ′

Laser-induced fluorescence spectroscopy of the secondary cataract
Optics and Spectroscopy, 2016Excitation–emission matrices of laser-induced fluorescence of lens capsule epithelium, the lens nucleus, and the lens capsule are investigated. A solid-state laser in combination with an optical parametric generator tunable in the range from 210 to 350 nm was used for excitation of fluorescence. The spectra of fluorescence of all three types of tissues

Laser induced fluorescence spectroscopy of boron carbide
Chemical Physics Letters, 2011Abstract Laser induced fluorescence spectrum of boron carbide (BC) between 490 and 560 nm has been recorded and analyzed. Gas-phase BC molecule was produced by the reaction of diborane and methane in the presence of magnesium atom from laser ablation process. The (0, 0), (1, 0), and (2, 0) bands of the B 4 Σ − – X 4 Σ − transition were rotationally

Laser-induced fluorescence spectroscopy of Hg2 excimers
International Laser Science Conference, 1986Pump-and-probe methods were used to excite high-lying I ( O u + ) and J(1 u ) states of Hg2, whose transitions to various lower states cause emission of fluorescence bands centered at 420 nm ( J 1 u →
