N2 - Polarization, broadening, and splitting in Fraunhofer-type absorption (FTA) spectra are observed in colinear Double-Pulse Lase-Induced Breakdown Spectroscopy (DP LIBS). Effects are attributable to the Optical Stark Effect (OSE) induced by the electric field of the second laser pulse within the first pulse-created plasma. This effect manifests exclusively in back-directed Laser-Induced Plasma (LIP) emission and during the presence of the second laser pulse. Notably, the OSE is absent in LIBS observations orthogonal to the direction of the laser beams.
