摘要

利用双晶形可变形反射镜对飞秒激光脉冲的成丝进行了实验研究,该实验可以控制成丝域的位置,确定光束截面上的丝和高强度通道的定位。利用掩模在波束的振幅分布中引入畸变,表明无法控制波束截面中细丝的数量和位置。

Influence of phase and amplitude distortions of initial beam profile on the characteristics of filamentation domain
The results of experimental research of the filamentation of femtosecond laser pulses using a bimorph deformable mirror, which allows controlling the position of the filamentation domain determining localization of filaments and high-intensity channels in the beam cross section. The introduction of distortions into the amplitude profile of the beam with using masks showed the inability to control the number and position of filaments in the beam cross section.
