A flow tagging technique based upon ionic fluorescence in strontium is investigated for applications to velocity measurements in gas flows. The method is based upon a combination of two laser based spectroscopic techniques, i.e. resonantly-enhanced i

Two fluorine-containing materials (NH4F and NaF) for optical fiber production have been analyzed with respect to their contents of Co, Cr, Mn and Ni using two different laser enhanced ionization (LEI) techniques, one using a rod-flame as an atomizati

Laser-enhanced ionisation spectrometry has been used to confirm 36 levels within the highly-excited 3d64s(6D)6d subconfiguration in Fe I that have been established by grating spectrometry. The new levels are used to identify ~ 200 lines in the UV gra

The thallium content in some natural waters (lakes, rivers and drinking water) in South-West Sweden has been determined by Laser-Induced Fluorescence in a Graphite Furnace (LIF-GF). The high sensitivity of the LIF-GF technique eliminated the need for

The behaviour of the lifetimes of the metastable 5d9 6s22D3/2 and 5d9 6s22D5/2 states in Au in an air/acetylene flame has been studied using the step-wise delayed laser-enhanced ionization technique. Using a new, fast and reliable, automated experime

The collisional dominated lifetimes of 9 metastable states of Au, Bi, Cd, Mg. Pb, and Sr in an acetylene/air flame have been measured by the step-wise delayed laser-enhanced ionization spectrometry technique. First, the dependency of the lifetime of

The lifetimes of atomic metastable states in an acetylene/air flame have been investigated using the laser‐enhanced ionization technique. The lifetimes were found to be several orders of magnitude less than the natural ones, which clearly shows tha

A technique for a fast and reliable determination of the lifetime of atomic metastable states in combustive situations, based on the laser-enhanced ionization technique, is developed. The typical time required for a determination of the lifetime of a
