Abstract
There is provided a laser unit that may include: a master oscillator configured to output a linear-polarized laser light beam; a first polarization device disposed in a light path of the linear-polarized laser light beam and provided with a polarization axis substantially aligned with a polarization direction of the linearly-polarized incident laser light beam; a second polarization device disposed in the light path of the linear-polarized laser light beam and provided with a polarization axis substantially aligned with a direction of the polarization axis of the first polarization device; and a laser amplifier disposed between the first polarization device and the second polarization device in the light path of the linear-polarized laser light beam and including a pair of discharge electrodes disposed to oppose each other, an opposing direction of the pair of discharge electrodes being substantially aligned with the direction of the polarization axis of the first polarization device.
