摘要
超强超短脉冲激光产生的高温、高密、强磁场等离子体与天体等离子体在许多方面都有很强的相似性 ,这使得某些天体物理过程的实验室模拟成为可能 .对天体等离子体中的铝发射谱进行了理论模拟 ,结果显示 ,利用激光等离子体的发射光谱 ,可以在实验室获得天体上难于观测的光谱范围并为天体物理学研究提供丰富的信息 .
High temperature, high density and strong magnetic fields in plasmas produced by ultra\|high intensity and ultrashort laser pulses are similar to the main characteristics of astrophysical plasmas. This makes it possible to simulate some astrophysical processes at laboratories. This paper presents our theoretic simulation of aluminum emission spectra in astrophysical plasmas. It can be concluded that using laser produced plasmas, we can obtain rich information on astrophysical spectroscopy, which is unobservable for astronomer.
