The electronic temperature, intensities of all lines and continuous spectra gradually increased with the increment of laser energy, and they got to maximum at different laser energy. our results of copper and aluminum show that there are possibly different thresholds of laser energy to electronic temperature and intensities of emission spectra of laser ablated plasma. at the different environmental gas pressure, spatial emission intensity distribution is explained by the competition among " heat reservoir effect ", " confined effect " and " s hadow effect "
認為cu等離子體羽的發光機制是由電子與粒子的碰撞傳能、電子與離子的復合形成的;隨激光能量的增加, cu等離子體特徵輻射(分立譜) 、連續背景輻射(連續譜) 、電子
溫度都出現最大值;結合對al的實驗結果說明:激光燒蝕金屬產生的等離子體,其特徵輻射、連續輻射、電子
溫度可能都存在一定的能量閾值;背景氣壓對激光燒蝕等離子體譜線的影響,其機理可以認為是「熱
庫效應」 、 「約束效應」及「陰影效應」相互競爭的綜合結果。
