Abstract
A spectroscopy system uses a probe laser beam and an opposing excitation laser beam, i.e., running opposite to a direction of the probe laser beam, but transmitted co-linearly with one another along a same optical path. A thermal lens effect acting on the probe laser beam allows for controlling alignment of the two laser beams and allows for supplementary measurements of parameters for the spectroscopy system based on geometric analysis of detected image signals. The alignment of the two laser beams is controlled by detection of the probe laser beam with respect to the effects of the excitation laser beam on a medium through which the two laser beams are passing.
