采用飞秒激光诱导击穿光谱（fs-LIBS）技术，在相同的实验条件下，对长春市净月国家森林公园、长春理工大学、一汽铸造厂和锻造厂等4个典型地点的白杨叶片中的元素含量进行了分析。从记录的光谱图中鉴别出白杨叶片中的N、P、K、Ca、Fe、Ti、Mn和Na等元素，并对光谱图进行自由校正，进而得到杨树叶片中元素的含量。结果表明，4个样点中，CF区白杨叶片中Ca、Fe含量最高，分别是JYP的2.05倍和1.66倍。实验表明，fs-LIBS可以用于分析样品中的元素含量，并在环境检测中找到新的应用。
Femtosecond laser-induced breakdown spectroscopy (fs-LIBS) is employed to analyze the element content in poplar tree leaves from four representative locations in Changchun City (Jingyue National Forest Park, JYP), Changchun University of Science and Technology (CUST), Casting Factory (CF) and Forging Factory (FF) of First Automobile Works (FAW) under identical experimental conditions. Those elements of N, P, K, Ca, Fe, Ti, Mn and Na are identified in the poplar tree leaves from the recorded spectrogram and the elemental content in the leaves is further obtained by applying free calibration method to the spectrogram. Our results show that the elements Ca and Fe in the poplar tree leaves from the CF area have the highest concentration in the four locations, which is a factor of 2.05 and 1.66 respectively to those of JYP. This experiment demonstrates that fs-LIBS can be utilized to analyze element content in a sample and find new applications in the environmental detection.
