| 摘 要： | 对均匀和非均匀分布的两种相位板调制下飞秒激光成丝过程进行理论研究。研究表明，两种情况下飞秒激光都形成模式可控的细丝阵列。对比发现，使用均匀相位板产生的细丝模式更为分隔清晰且稳定，而非均匀分布的相位板使激光形成的细丝阵列长度更长。

| Abstract: | The distribution and evolution of filamentation of femtosecond laser pulses with the chessboard-like and grid-like phase plates, respectively, in air are numerically studied. It is demonstrated that the filamentation can be controlled by using the two phase plates. More clearly separated and more stable filaments are formed by using the chessboard-like phase plate, while longer filaments are formed by using the grid-like phase plate. |
