AB  - The annular laser beam (ALB) is widely used in many fields, which could be 
      affected by laser power and beam quality. To effectively and flexibly improve the 
      beam quality of high-power large-aperture thin-wall ALB, a two-stage enlargement 
      and adaptive correction configuration (TEACC) consisting of a novel outer-surface 
      tubular deformable mirror (OTDM) and two extra prism groups (EPGs) is proposed in 
      this paper. The correction principle and design principle of the TEACC are 
      derived and analyzed. Based on the principle, a typical OTDM prototype and EPG 
      structure are designed. Annular aberrations are compensated by applying the 
      OTDM's influence functions and the least-square algorithm in simulation. The 
      results show that the TEACC could perfectly compensate the wavefront distortions 
      described by the 2(nd) to 36(th) order Zernike annular aberrations.
