|1. (WO2015045098) LASER APPARATUS AND EXTREME ULTRAVIOLET LIGHT GENERATION SYSTEM|
|Title:||LASER APPARATUS AND EXTREME ULTRAVIOLET LIGHT GENERATION SYSTEM|
[Problem] To acquire high-output laser light. [Solution] The present invention may be provided with: a first polarization device having a polarization axis in a direction substantially matching the polarization direction of laser light of incident linearly polarized light; a second polarization device having a polarization axis in a direction substantially matching the direction of the polarization axis of the first polarization device; and a laser amplifier, which includes a pair of discharge electrodes disposed opposite each other so that the opposing directions substantially match the directions of the polarization axis of the first polarization device, and which is disposed between the first polarization device and the second polarization device.
