摘要

为了满足特定的需求或提高系统的能源效率,有必要将光束集成为特定的强度分布光束。本文在混合区域振幅自由(MRAF)算法的基础上建立了一套规则,并提出了一种通过设置能量效率来计算强度分布的波束整形算法。仿真结果表明,与传统的Gerchberg-Saxton (GS)算法相比,放弃控制一小部分能量后,收敛效果提高了1 ~ 2个数量级;与MRAF算法相比,能效收敛到预设目标值,且在相同收敛强度下能效更高。该算法为飞秒激光加工技术中的整形提供了一条新的路径。

Improvement of MRAF algorithm based on high energy efficiency for beam shaping
To meet the specific needs or improve the system’s energy efficiency, it is necessary to integrate the beam into a specific intensity distribution beam. This paper establishes a set of rules based on the mixed-region amplitude freedom (MRAF) algorithm, and a beam shaping algorithm is proposed to calculate the intensity distribution by setting the energy efficiency. Simulation results show that compared with the traditional Gerchberg–Saxton (GS) algorithm, the convergence effect improved by one to two orders of magnitude after abandoning controlling a small part of the energy; compared with the MRAF algorithm, the energy efficiency converged to the preset target value, in addition, the energy efficiency is higher under the same convergence intensity. This algorithm provides a new path for shaping in femtosecond laser processing technology.
