    摘要: A spatial filter includes a first filter element and a second filter element overlapping with the first filter element. The first filter element includes a first pair of cylindrical lenses separated by a first distance. Each of the first pair of cylindrical lenses has a first focal length. The first filter element also includes a first longitudinal slit filter positioned between the first pair of cylindrical lenses. The second filter element includes a second pair of cylindrical lenses separated by a second distance. Each of the second pair of cylindrical lenses has a second focal length. The second filter element also includes a second longitudinal slit filter positioned between the second pair of cylindrical lenses.

    摘要: A laser amplifier includes an input aperture operable to receive laser radiation having a first polarization, an output aperture coupled to the input aperture by an optical path, and a polarizer disposed along an optical path. A transmission axis of the polarizer is aligned with the first polarization. The laser amplifier also includes n optical switch disposed along the optical path. The optical switch is operable to pass the laser radiation when operated in a first state and to reflect the laser radiation when operated in a second state. The laser amplifier further includes an optical gain element disposed along the optical path and a polarization rotation device disposed along the optical path.

    摘要: 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.
