FIELD: experimental physics.
SUBSTANCE: invention relates to a section of experimental physics, to a gas target, which can be used in the study of the interaction of powerful laser radiation with gaseous media, in particular effects of generation in gases of high-order harmonics, electron acceleration in an electric field accompanying a laser pulse, generation in laser plasmas of betatron radiation and short-wave radiation of multicharged ions. The gas target includes a sealed gas-filled chamber, the first end wall of which contains the first window closed with metal film of material destructible with laser radiation with a thickness of no more than 0.2 mcm, capable of withstanding pressure of at least 1 atm. Moreover, a chamber sidewall has a hole for gas inlet to the chamber. The amount of film substance destructed by laser radiation should not exceed the amount of substance of chamber gas content.
EFFECT: prevalence of effects of the interaction of a laser pulse with gas over effects of the interaction of the laser pulse with substance of an input window of a gas target by creation of a sharp boundary between gas and vacuum, with a boundary width not exceeding a length of laser beam constriction.
