Title:
WAVEFRONT CONTROL DEVICE AND ADAPTIVE OPTICS DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/027104
Kind Code:
A1
Abstract:
A wavefront control device to which the present invention is applied is provided with: an optical frequency comb generation unit that emits an optical frequency comb having a plurality of optical pulses disposed in numerical order on a time axis; and a wavefront synthesis unit that distributes the plurality of optical pulses of the optical frequency comb incident from the optical frequency comb generation unit to positions different from each other according to the relative phases thereof with respect to the first optical pulse on a plane crossing the traveling direction of the optical frequency comb, and generates a synthesized wavefront of the optical pulses emitted from the positions different from each other. The optical frequency comb generation unit is provided with a phase control unit that controls the repetition frequency and offset frequency of the optical frequency comb.
