摘要 针对惯性约束聚变(ICF)驱动装置,提出一种新的焦斑整形方法:基于衍射叠加原理,采用自适应光学(AO)技术调整近场相位来实现对远场焦斑形态的控制。以一种新型的变形镜模型——压电薄膜变形镜(PFDM)为例,对AO技术用于焦斑整形的可行性进行了模拟研究。结果表明,在制作工艺允许的范围内,当变形镜的空间分辨率达到一定程度时,便可利用AO技术实现良好的焦斑整形效果,而且能够保证焦斑较好的均匀性。进一步研究结果表明,该方法对波前畸变的容忍度要优于传统方法。 A novel method based on diffraction theory with adaptive optics to control far field irradiance profile in inertial confinement fusion device is proposed.Taking piezoelectricity film deformable mirror for example,the probability of this method used in profile control is studied.The results show that adaptive optics technique can be used to control the far-field intensity profile and uniformity easily by deformable mirror with high spatial resolution.In addition,more simulations show that this method is better than traditional method in the tolerance of wavefront distortion.
