- Length variable gas target and laser-gas reaction system comprising the same

摘要

The present invention relates to a length-adjustable gas target capable of easily adjusting an effective length of the gas target which is represented by a gas density cross section while uniformly maintaining the gas density cross section by arranging an insertion portion movable to slide on one end of the gas target inside a density distribution forming part. Provided is the gas target which includes the density distribution forming part that is a space in which a length is adjustable and in which the length of the density cross section of a gas received in the density distribution forming part is adjustable according to the length of the density distribution forming part.
