研究了气态乙烯在飞秒激光丝中的光化学反应。结果表明，氢化非晶碳（a-C：H）薄膜和纳米颗粒是通过与强激光场的强相互作用产生的。10（13）Wcm（-2））。激光场强度是决定薄膜中sp（2）/sp（3）碳比以及纳米颗粒尺寸和数量的重要参数。
Photochemical reactions of gaseous ethylene in femtosecond laser filaments are studied. It is shown that hydrogenated amorphous carbon (a-C:H) films and nanoparticles are produced by the strong interactions with the intense laser fields (ca. 10(13)Wcm(-2)). The laser field intensity is found to be an important parameter to determine the sp(2)/sp(3) carbon ratio of the films and the size and number of nanoparticles.
