摘要： An electromagnetic pulse protection method comprising: a search step in which searches are conducted for threats 2 that generate an electromagnetic pulse 2a; and a generation step in which laser light 5 is focused on a focal point 4 and plasma 6 is generated at the focal point 4, if a threat 2 is found in the search step. As a result, a variety of objects to be protected, including objects to be protected for which electrical openings are indispensable can be protected from electromagnetic pulse attacks.

摘要： A laser oscillation cooling device (100) includes a light emitting section (1) that emits laser excitation light (Z1), a laser excitation section (2) that excites the laser excitation light (Z1) to emit laser light (Z2) and has a heat generating region (S) where heat is locally generated, a storage tank (3) capable of storing an extremely low temperature liquid (L), a pressurizing section (31) that brings the extremely low temperature liquid (L) into a sub-cool state by pressurizing the inside of the storage tank (3), and a jetting supply section (4) that removes heat from the laser excitation section (2) by jetting the extremely low temperature liquid (L) in the sub-cool state from a plurality of jet ports arrayed in a two-dimensional manner to the laser excitation section (2).

摘要： A method of irradiating an electromagnetic pulse includes specifying a position of a target having electronic equipment; setting the light-condensing point based on the position of the target; and condensing the laser beam to generate plasma in the light-condensing point such that the electromagnetic pulse generated from the plasma is irradiated to the electronic equipment. In this way, a method and system for irradiating an electromagnetic pulse are realized which can irradiate the electromagnetic pulse of a large output while restraining diffusion of the electromagnetic pulse.
