    Abstract: An extreme ultraviolet light (EUV) generation system is configured to improve conversion efficiency of energy of a laser system to EUV energy by improving the efficiency of plasma generation. The EUV generation system includes a target generation unit configured to output a target toward a plasma generation region in a chamber. The laser system is configured to generate a first pre-pulse laser beam, a second pre-pulse laser beam, and a main pulse laser beam so that the target is irradiated with the first pre-pulse laser beam, the second pre-pulse laser beam, and the main pulse laser beam in this order. In addition, the EUV generation system includes a controller configured to control the laser system so that a fluence of the second pre-pulse laser beam is equal to or higher than 1 J/cm2 and equal to or lower than a fluence of the main pulse laser beam.

    Abstract: An extreme ultraviolet light generation apparatus may include: a chamber including a plasma generation region to which a target is supplied, the target being turned into plasma so that extreme ultraviolet light is generated in the chamber; a target supply part configured to supply the target to the plasma generation region by outputting the target as a droplet into the chamber; a droplet detector configured to detect the droplet traveling from the target supply part to the plasma generation region; an imaging part configured to capture an image of an imaging region containing the plasma generation region in the chamber; and a controller configured to control an imaging timing at which the imaging part captures the image of the imaging region, based on a detection timing at which the droplet detector detects the droplet.
