    在激光焊接過程中,當被焊材料受到高能激光束作用時,其表面會迅速熔化、氣化,與外加的保護氣體一起在被焊區域的上方電離形成等離子體雲。
  2. The main work of this dissertation focuses on the analysis and design theory for a resonator with diffraction optical elements by using a matrix eigenvalue method. the principle and method how to realize a low diffraction beam have been described. both the experimental and theoretical results show that the low diffraction beam has great advantages over the gaussian beam in an ablation - dominated material removal processes
