Unique features of lasers, such as spatial and temporal coherence, low divergence, high power density and monochromaticity, endorse a broad spectrum of applications in fabricating nanostructured materials. Based on laser-material interactions, such as localized heating, optical near–field effect, ablation, and resonant excitation, a number of laser–assisted techniques, laser exfoliation, laser direct writing, laser–assisted chemical vapor deposition, and laser–assisted combustion synthesis, were developed in our group for fabricating carbon nanostructures of different dimensionalities, including two–dimensional graphene, one dimensional carbon nanotubes, and zero–dimensional carbon nanoonions.

Due to its versatile bonding and atomic arrangements, the element carbon is capable of forming multiple allotropes, as shown in (Figure 1), and exhibits diverse properties [1]. The discovery of buckminsterfullerene (C60) [2] opened a magic door towards the fairyland of carbon nanostructures followed by consecutive discoveries of fullerenes, [2–6] carbon nanotubes (CNTs), [7] and graphene,[8, 9] which are then recognized as new carbon allotropes. Based on their dimensionalities, the new carbon nanostructures can be classified into three major categories, including zero–dimensional (0D) fullerenes and carbon nanoonions (CNOs), one dimensional (1D) CNTs and carbon nanoscrolls (CNSs), and two–dimensional (2D) graphene.
