Abstract
An extreme ultraviolet light generation device may include: a chamber in which extreme ultraviolet light is generated from plasma generated by irradiating a target with laser light output by a laser device, in a generation region therein; a target supply unit configured to output the target as a droplet toward the generation region; a droplet detector configured to detect the droplet in a detection region; and a controller. The droplet detector may transmit, to the controller, a pass timing signal indicating a timing when the droplet passes through the detection region. The controller may include a noise compensation unit configured to compensate for noise of the pass timing signal caused by an electromagnetic wave from the plasma, and transmit a trigger signal that gives a trigger to output the laser light to the laser device based on the pass timing signal in which the noise is compensated for.
