摘要：
High temperature aluminum plasmas have been produced by irradiating the layered Au-Al foils with the smoothed high power laser at the Xingguang II laser facility. High-resolution transmission spectrum of the Al plasma has been measured by using penta-erythritol tetrakis (hydroxymethy) methane C(CH2OH)(4) crystal spectrometer. Absorption lines of the aluminum ion transition 1s-np(n=3,4,5) in the region of 0.61-0.70 nm, have been observed and identified. The unresolved transition array model has been introduced to calculate the transmission spectra of aluminum plasma. The measured transmission spectrum has been compared with those calculated.
