Abstract:
1. A multi-conjugate adaptive optics system for reducing aberration-induced fluctuations in a beam, the system comprising: a first wavefront corrector configured to correct a wavefront of a beam; a first wavefront sensor configured to measure the wavefront of the beam corrected by said first wavefront corrector, wherein said first wavefront sensor and said first wavefront corrector are conjugated to a first plane; a second wavefront corrector configured to correct the wavefront of the beam corrected by said first wavefront corrector; and a second wavefront sensor configured to measure the wavefront of the beam corrected by said second wavefront corrector, wherein said second wavefront sensor and said second wavefront corrector are conjugated to a second plane separated from the first plane, wherein said first wavefront corrector is configured to correct the wavefront based on the measurement of said first wavefront sensor, and said second wavefront corrector is configured to correct the wavefront based on the measurement of said second wavefront sensor.
