Brewster window polarizer is used in the laser cavity to transmit 100% of p-polarized component without reflection losses and to introduce losses for s-polarized component.

Total reflection of s-polarized component from the Brewster window is up to 22 % for UVFS and up to 26% for N-BK7 at 1064 nm.
