Abstract Al plasma was obtained by a pulsed laser beam, which was produced from a Nd:YAG laser set with Q-switch, ablating metal target Al in Ar. Based on the plasma, radiation of the plasma was recorded with time- and space-resolved technology, so Al characteristic radiation spectra were obtained. According to the spectra, the coupling of aluminum 3p electronic angular momentums was simplified as quasi-hydrogen particle. At the same time, the main quantum and orbit angular quantum shielding coefficients of aluminum nucleus, signed as α and s respectively, were carefully figured out with related theories of quantum mechanics. With our experiment, the resonance double lines of aluminum were scaled up at 396.15 and 394.40 nm respectively. As a result of our calculation, the main quantum shielding coefficient of aluminum nucleus was σ=10.850 359, and the orbit angular quantum one was s=7.332 875. Their values were reasonable in terms of the order of magnitude.
