The role of the Zeeman effect for the power enhancement of a small-bore argon ion laser (488.0 nm) by applying the transverse magnetic field has been investigated both experimentally and theoretically. The sigma-polarized laser has a larger output power than the ..pi.. polarized laser in the wide range of magnetic field strength. Specifically, at weak magnetic fields, enhancement occurred only for the sigma polarized laser. The experimental results are interpreted in terms of the semiclassical theory of the Zeeman laser. A narrow spectrum envelope is observed in the sigma-polarized laser. In the case of internal mirrors without Brewster window, it is demonstrated experimentally that ..pi.. and sigma polarization coexist and compete with each other.
