A polarizer of 193 nm was fabricated with several silicon plates which were mounted so as to incident the UV light of 193 nm by Brewster angle. Its transmission rate is 60% and the polarization extinction ratio is 20:1. Compared with using natural 193 nm light, the high isotropic enhancement of Yb 3+-doped fiber phase-shifted distributed feedback (DFB) lasers was found by using the 193 nm polarized light, of which the UV polarization lies in the plane of the irradiating beams and the fiber axis.
