Title: Method and system for compact and efficient high energy pulsed laser amplifier

Abstract

An optical amplifier system includes an input aperture operable to receive light propagating along an optical path in a first direction and a first polarizer disposed along the optical path. The first polarizer is operable to pass light having a polarization state aligned with a first polarization axis. The system also includes a first Pockels cell operable to receive light passing through the first polarizer, an optical gain element disposed along the optical path, a second Pockels cell disposed along the optical path, and a second polarizer disposed along the optical path. The second polarizer is operable to pass light having a polarization state aligned with the first polarization axis. The system further includes a first mirror operable to receive light reflected from the second polarizer, a second mirror operable to receive light reflected from the first polarizer, and an output aperture operable to transmit light passing through the second polarizer.
