Abstract

The invention relates to an optical beam deflecting and purifying device based on a random paralleling optimal algorithm. The device controls optical beam deflection and simultaneously achieves optical beam purification by utilizing a deformed reflecting mirror as an optical beam control device. In the random paralleling optimal algorithm, target light intensity distribution is taken as an evaluation function; optical beam positional information and optical beam quality information are taken as an identical criterion; and closed loop control is conducted to the deformed mirror according to a criterion provided in an optical beam quality evaluation system, so that the criterion of the optical beam positional information and the optical beam quality information achieves an extreme value, thereby simultaneously achieving the optical beam defection and the optical beam purification.

Description

technical field [0001] The invention relates to a beam control method, in particular to a device based on a random parallel optimization algorithm, which can realize beam deflection and purification at the same time. Background technique [0002] Beam deflection and purification have been widely used in the field of high-energy laser technology. In a high-energy laser system, factors such as uneven distribution of the refractive index of the laser medium, misalignment of the resonator, and surface error caused by the limitation of processing precision of optical components will cause distortion of the wavefront of the output beam of the laser and reduce the quality of the beam. Therefore, beam purification measures must be taken Corrects wavefront distortion to improve beam quality. On the other hand, dexterous and fast beam deflection control is the guarantee to achieve target tracking and laser precision strike. Most of the existing technical approaches use the mechanica...
