Abstract

Experimental and theoretical study of the post-filamentation stage of focused high-power Ti:Sa laser pulses in air is presented. Angular divergence of the laser beam, as well as angular and spatial characteristics of specific spatially localized light structures, the post-filament channels (PFCs), under different initial focusing conditions and laser beam energy are investigated. We show that PFC angular divergence is always less than that of the whole laser beam and tends to decrease with laser pulse energy increase and beam focal length elongation.

超短激光脉冲在空气中自聚焦后形成的高强度光通道
对高功率Ti:Sa激光脉冲在空气中聚焦后成丝阶段进行了实验和理论研究。研究了不同初始聚焦条件和激光束能量下,激光光束的角散度以及特定空间定域光结构——后丝通道(pfc)的角和空间特性。结果表明,PFC的角散度始终小于整个激光束的角散度,并随着激光脉冲能量的增加和光束焦距的延长而减小。
