Abstract:
The extreme ultraviolet light generating apparatus includes a target supply unit to output a target, a driver laser to output a driver laser beam with which the target is irradiated, a guide laser to output a guide laser beam, a beam combiner to have optical paths of the driver laser beam and the guide laser beam substantially coincide with each other and output these beams, a first optical element including a first actuator to adjust an optical path of the driver laser beam to be incident on the beam combiner, a second optical element including a second actuator to adjust an optical path of the guide laser beam to be incident on the beam combiner, a sensor to detect the guide laser beam outputted from the beam combiner to output detected data, and a controller to receive the detected data, control the second actuator based on the detected data, and control the first actuator based on an amount of controlling of the second actuator.

Claim (Index 5):
An extreme ultraviolet light generating apparatus comprising:\n a target supply unit configured to output a target toward a predetermined region; a pre-pulse laser configured to output a pre-pulse laser beam with which the target is irradiated; a main pulse laser configured to output a main pulse laser beam with which the target is irradiated after the target is irradiated with the pre-pulse laser beam; a first guide laser configured to output a first guide laser beam; a second guide laser configured to output a second guide laser bam; a first beam combiner configured to have an optical path of the pre-pulse laser beam outputted from the pre-pulse laser and an optical path of the first guide laser beam outputted from the first guide laser substantially coincide with each other and output the pre-pulse laser beam and the first guide laser beam; a second beam combiner configured to have an optical path of the main pulse laser beam outputted from the main pulse laser and an optical path of the second guide laser beam outputted from the second guide laser substantially coincide with each other and output the main pulse laser beam and the second guide laser beam; a first optical element including a first actuator configured to adjust an optical path of the pre-pulse laser beam to be incident on the first beam combiner; a second optical element including a second actuator configured to adjust an optical path of the first guide laser beam to be incident on the first beam combiner; a third optical element including a third actuator configured to adjust optical paths of the pre-pulse laser beam and the first guide laser beam each outputted from the first beam combiner; a fourth optical element including a fourth actuator configured to adjust an optical path of the main pulse laser beam to be incident on the second beam combiner; a fifth optical element including a fifth actuator configured to adjust an optical path of the second guide laser beam to be incident on the second bears; combiner; a sixth optical element including a sixth actuator configured to adjust optical paths of the main pulse laser beam and the second guide laser beam each outputted from the second beam combiner; a third beam combiner configured to have an optical path of the pre-pulse laser beam outputted from the third optical element and an optical path of the main pulse laser beam outputted from the sixth optical element substantially coincide with each other and have an optical path of the first guide laser beam outputted from the third optical element and an optical path of the second guide laser beam outputted from the sixth optical element substantially coincide with each other; a sensor configured to detect the first and second guide laser beams outputted from the third beam combiner to output detected data; and a controller configured to control the second actuator based on the detected data on the first guide laser beam detected by the sensor, control the first actuator based on an amount of controlling of the second actuator, control the fifth actuator based on the detected data on the second guide laser beam detected by the sensor, and control the fourth actuator based on an amount of controlling of the fifth actuator.
