“…The DM operates with a low-power beam with a pulse repetition rate of 100 Hz. The wavefront is measured with a Hartmann sensor [ 89 , 90 ] , and the quality of focusing is measured with a charge-coupled device (CCD) camera that records the energy distribution in the far-field. Two sets of sensors are used and, accordingly, two feedbacks, shown in Figure 14 by yellow lines.…”

“…Wavefront φ measurements by an HS are based on the estimations of local slopes of a distorted wavefront ∂φ∕∂n versus some ideal ones [6,7]. The whole wavefront is divided into several subapertures by a set of diaphragms (Hartmann mask) and the deviation of the light spot at the sensing plane with respect to some reference position in each subaperture is measured.…”

“…The accurate acquisition of the thermal distortion of a single optical surface is essentially important to the design and control of the high-power laser. Shack-Hartmann wavefront sensing (SHWFS) is widely used to measure the wavefront distortion of the laser beam in high-power laser facilities, including the National Ignition Facility [6,7], the Laser MégaJoule Facility [8], the OMEGA extended performance Laser System, and the Chinese ICF Facility [9]. However, the SHWFS mainly focuses on the wavefront distortion measurement of the whole system.…”
