在加热的流动管中，在冷凝蒸汽中直接激光蒸发过渡金属/石墨复合棒产生单壁碳纳米管（SWT）。一个更高的产量的纳米管被发现，与金属催化的电弧放电方法所产生的那些上的无定形涂层很少。Co与Ni的混合物催化约50%的所有碳蒸发到SWT。SWT增长的模型，目前的情况下，是在金属颗粒的尺寸是有限的，由于并发的碳冷凝。
Direct laser vaporization of transition-metal/graphite composite rods produced single-walled carbon nanotubes (SWT) in the condensing vapor in a heated flow tube. A much higher yield of nanotubes was found, with little of the amorphous overcoating on those produced by the metal-catalyzed are-discharge method. A mixture of Co with Ni catalyzed about 50% of all the carbon vaporized to SWT. A model for SWT growth is presented for both the present case and the are in which the metal particle size is limited due to the concurrent carbon condensation.
