We report a systematic study of the generation line polarization of optically pumped Laser Induced Plasma Lasers. Results are presented for the elements of the 13th group with ground state configuration ns np 2P1∕2;3∕2. Degree of polarization depends on pumping light polarization, spin states of ground, and pumped electronic levels. The external magnetic field directed perpendicularly to the magnetic vector of a plasma laser strongly reduces its degree of polarization. It is proposed that the self-generated magnetic field induced by the pumping beam in the plasma is responsible for the polarization effects. The strength of this self-generated magnetic field is about 200 mT.
