Spectroscopic investigation of atomic and molecular species formed in a laser microprobe plasma using a wavelenth calibrated tunable dye laser

Creator:

Beenen, Gerhard Joseph

Abstract:

The temporal and spatial characteristics of a laser microprobe plume were investigated using the spectroscopic methods of emission, absorption and fluorescence. The plume was produced by rapid vaporization of a small quantity (1 μg) of a solid sample using a focussed pulsed dye laser (110 MW/cm²). For absorption and fluorescence...
