LINEAR ADAPTIVE OPTICS SYSTEM IN LOW POWER BEAM PATH AND METHOD |
摘要 |
A system and method for providing a wavefront corrected high-energy beam of electromagnetic energy. In the illustrative embodiment, the system includes a source of a first beam of electromagnetic energy; an amplifier for amplifying said beam to provide a second beam; a sensor for sensing aberration in said second beam and providing an error signal in response thereto; a processor for processing said error signal and providing a correction signal in response thereto; and a spatial light modulator responsive to said correction signal for adjusting said beam to facilitate a correction of said aberration thereof. In more specific embodiments, the source is a laser and the sensor is a laser wavefront sensor. A mirror is disposed between said modulator and said sensor for sampling said beam. The mirror has an optical thin- film dielectric coating on at least one optical surface thereof. The coating is effective to sample said beam and transmit a low power sample thereof to said means for sensing aberration. The processor is an adaptive optics processor. The spatial light modulator may be a micro electro-mechanical system deformable mirror or an optical phased array. In the illustrative embodiment, the source is a master oscillator and the amplifier is a power amplifier beamline. An outcoupler is disposed between the oscillator and the amplifier. |
