Significance In high-power infrared laser systems,monocrystalline silicon reflectors are widely used,and the reflectors need to achieve high-precision,high-stability beam transmission under high-power laser irradiation for long durations.The high accuracy of components and laser load capacity are both highly desired.With the continuous development of high-energy laser technology,the performance of existing monocrystalline silicon components has been unable to support the further improvement of system output power and performance,which has become a technical shortcoming.A high-energy laser system requires optimum reflector performance in systems,i.e.,precision and laser load capacity.The pursuit of full-frequency spatial error restraint and reduction of laser energy absorption rate depends on fabrication quality.However,at present,fabrication technology inherits from traditional optical processing,and it is difficult to achieve both precision and laser load capability.Accordingly,it is necessary to investigate manufacturing methods and processes and combine innovative manufacturing techniques with application characteristics.By discussing the present situation and key technology of monocrystalline silicon component manufacturing,we hope technical support for realizing nanoprecision shape control manufacturing of monocrystalline silicon can be provided.Progress This article summarizes the current status of and difficulties in manufacturing high-energy laser aspheric components and reveals the typical processing defect morphology and generation mechanism that reduce the laser load capacity.Based on the realization of high-precision processing of aspherical components,the role of new methods of controllable flexible body processing based on immersion smooth polishing,ion beam sputtering cleaning,and other methods in controlling defects is discussed to realize the formation of high-energy laser aspherical components.The specific research includes the following aspects:(1)Nanoprecision surface shape control manufacturi
