Characteristics of Airy Beams Generated with Deformable Mirrors
摘要
对基于变形镜(DM)生成的Airy光束进行了光束特性研究。采用Zernike多项式对立方相位进行分解,建立了由多个Zernike多项式线性组合的相位调谐模型,并对组合中的每一个Zernike多项式引入一个系数。模拟分析了不同Zernike多项式系数对Airy光束结构和光束质量的影响。利用69单元变形镜进行了Airy光束生成实验,测试分析了不同系数组合下的Airy光束强度分布,通过控制Zernike多项式系数实现了Airy光束特性的控制。
Abstract
The current research investigates the characteristics of Airy beams generated with deformable mirrors (DM). After the Zernike polynomial was used to decompose their phases, a phase-tuning model consisting of linear combinations of multiple Zernike polynomials was established, and a coefficient was introduced for each polynomial in the combination. Then, the effects of different Zernike polynomial coefficients on the Airy beam structure and quality were simulated. The Airy beam generation experiment was conducted using a 69-unit deformable mirror, and the beam intensity distribution under different coefficient combinations was tested and analyzed. The beam characteristics of Airy beam can be controlled by the adjustment of Zernike polynomial coefficients.
