Abstract

Two acoustooptical deflectors placed orthogonal to each other allow the scanning of a laser beam in two dimensions without mechanical movement. A complete scan is possible in 50 μs, providing a spatial resolution of 20 × 125 spots. This is used to follow the development of plumes generated by laser vaporization from a surface. Both Na atoms and Pb₂ dimers can be monitored by absorption over the lifetime of the plume. The use of a second channel in the transient digitizer allows normalization to correct for variations in laser intensity and deflection efficiencies during the scan. Concentration maps for each can thus be obtained.
