Abstract

We propose a model explaining polarization effects in laser-induced plasma lasers (LIPLs) of the 13th group elements, pumped by a linearly polarized laser beam. The model is based on considering optical transitions between magnetic sublevels involved in the pumping-generation cycle. The model reproduces experimentally observed LIPL polarization features under the np 2P1/2, 3/2 → n′s 2S1/2 pumping. On the other hand, polarization-resolved collisional-radiative modeling appears to be required for a quantitative explanation of the LIPL polarization when the np 2P1/2, 3/2 → n′d 2D1/2 pumping is used.
