US 2025/0149192 A1 · PLASMA AND GAS BASED OPTICAL COMPONENTS TO CONTROL RADIATION DAMAGE

Abstract

Plasma and gas based optics may be used to direct light to a target that produces emission harmful to solid-state optics. In some cases, a shield having a hole, opening or separation for the light to pass may be employed to attenuate or block such harmful emission from the target thereby providing some protection for the solid-state optics. In some designs, the light incident on the target is not coaxial with light sources such as pump and/or seed sources providing beams incident on the plasma or gas based optics. In various designs, however, the plasma or gas based optic(s) is resistant to the emissions from the target.

Dependent claims

A plasma based optical system comprising:

a gas source for providing gas to a beam amplification region for producing a plasma;
a seed beam source arranged to direct an input seed beam into the beam amplification region;
at least two beam pump sources arranged to direct pump beams into the beam amplification region for amplifying the input seed beam into an amplified output beam directed at a target, and wherein the at least two beam pump sources are located off-axis of the amplified output beam;
and
a radiation shield having a hole and positioned between the beam amplification region and the target so that the amplified output beam is directed through the hole while the at least two beam pump sources are protected from radiation produced by the target due to their off-axis locations.
