Laser beam transmitter
TLDR
In this paper, the laser beam transmitter consists of an incident side plane mirror, a side parabolic mirror, an exit side paraboloid mirror, and an exit-side plane mirror.Abstract:
PURPOSE:To obtain an intended beam profile while preventing lowering of beam strength, divergence of beam and disturbance of beam pattern. CONSTITUTION:The laser beam transmitter-comprises an incident side plane mirror 1a, an incident side parabolic mirror 2a, an exit side parabolic mirror 2b, and an exit side plane mirror 1b. The parabolic mirrors 2a, 2b are arranged such that a beam can impinge and reflect thereon while shifting the axes. The mirrors 1a, 1b, 2a, and 2b are arranged on a common plane.read more

Regenerative amplifier, laser apparatus, and extreme ultraviolet light generation system
TL;DR: In this article, a regenerative amplifier is used in combination with a laser device, and the regenerative amplifiers may include: a pair of resonator mirrors constituting an optical resonator; a slab amplifier provided between the pair of the resonator mirror for amplifying a laser beam with a predetermined wavelength outputted from the laser device; and an optical system disposed to configure a multipass optical path along which the laser beam is reciprocated inside the slab amplifier.
