| 摘 要： | 利用掠入射反射短波截止原理,成功地实现了平场光栅谱仪的无级次重叠摄谱.实验结果表明,利用该方法来消除平场光栅谱仪中短波长的高级谱对所考察波段的一级谱的影响是简便而有效的.实验获得了镁激光等离子体在4.4～5.6nm,5.9～11.8nm,7.0～14.0nm三个不同波段的近似的纯一级谱.

| Abstract: | The performance of double reflecting mirrors as a reflection filter used with a grazing incidence flat-field grating spectrometer has been experimentally investigated. We have achieved "pure" first-order spectrum of Mg laser-produced plasma in some spectral regions. The result shows that the double mirrors reflection filter is very simple and useful to eliminate order overlapping in grazing incidence flat-field grating spectrometer. |
