Abstract
Laser-induced fluorescence spectroscopy is applied to beryllium evaporated from a Knudsen cell at T=1400 K. Beryllium atoms are excited at lambda -235 nm and lambda =166 nm. The pump radiation is generated by stimulated anti-Stokes Raman scattering of dye-laser radiation. The fluorescence signals are calibrated by micro-balancing with a quartz crystal. Concentrations as low as 108 cm-3 can be measured in this experiment.Keywords
