Fig. 2. (a) Filament-induced breakdown spectra of Al under different polarizer angles of −15°, 15°, 45°, 60°, and 105°. −25° was corresponding to the polarization plane of the laser beam. The energy before L1 was 6.22 mJ, and the pulse duration was 30 fs. (b) Integration range used to calculate the integral intensity of Al I 396.152 nm and its background.
