Diode laser progress

Gavish L, Perez LS, Reissman P, Gertz SD (2008) Irradiation with 780 nm diode laser attenuates inflammatory cytokines but upregulates nitric oxide in lipopolysaccharide-stimulated macrophages implications for the prevention of aneurysm progression. Lasers Surg Med 40(5) 371-378... [Pg.274]

Einstein A coefficient in its (001-000) transition at 2349 cm -1 than that for the corresponding band at 2223 cm -1 in NzO, appears always to be the minor triatomic product emitting in this range. Although these results are presently preliminary (and their interpretation may need to be revised if, for example, rates of relaxation of the excited products are distorting the partially relaxed vibrational distributions), they seem incompatible with the diode laser observations unless reaction (18) produces C02 substantially in vibrational levels with v3 = 0. Further experiments are in progress. [Pg.47]

Experiments are currently in progress to measure CO and NO concentrations in a flat flame burner by diode laser spectroscopy. Comparative measurements are also being made using microprobe sampling with subsequent analysis by non-dispersive infrared and chemiluminescent techniques. Some preliminary laser absorption results for CO are reported here initial results for NO have been published separately (4). Also reported are initial data for collision halfwidths in combustion gases. [Pg.418]

Determination of the branching ratio for the product channels in reaction of CH3COOH with OH radicals in a smog chamber under atmospheric conditions by measuring the CO2 formation yield (CW-CRDS using a distributed feedback diode laser at 1570 nm) is in progress. [Pg.190]
