Abstract
In a multi-pass laser optical system orthogonal polarization of any two immediately adjacent optical passes allows suppression of internal parasitics caused by overlap of laser radiation on successive passes through a laser oscillator or amplifier, allowing increased operating efficiency and closer spacing of adjacent optical paths.
