Nanomaterials and lasers both are the highly emergent and hot topic of research
recent days. Lasers have shown their potential application in the processing of materials and
their characterizations. Laser cutting, drilling, alloying, welding, defect creation inside the
bulk etc. are some conventional applications of lasers in bulk materials processing, while
there are number of approaches for the processing of nanoscale materials using lasers.
Availability of high power (up to peta- watt), wavelength from soft X-ray to microwave,
short pulse width (ps-, fs- to atto- second), few hertz to MHz frequency laser sources and
continuous research and development on lasers have fuelled research and development in
the area of laser processing of nano-structured materials. Lasers have the utility not only in
the processing of nanostructures, but they can modify size, shape, phase, morphology and
hence properties of the nano-structured materials. All the methods of laser processing of
nanostructures are almost simple, quick, one step and green and produce materials having
surfaces free from chemical contamination. Such materials are highly important for biological and medical applications, where purity of the materials is of highest impact.
Pulsed Laser ablation (PLA) of solid target materials in vacuum, gases and air with
collections of clusters on the substrates provide synthesis of excellent 0D, 1D and 2D metal,
metal oxide and ceramic nanostructures. High pressure PLD causes generation of
nanoparticles inside the Plume, which acts as catalysts for the growth of 1D nanostructures
and known as nanoparticle assisted pulsed laser deposition (NAPLD), similarly, PLA in the
thermal furnace and collection of materials on substrates also produces highly crystalline
nanostructures and the process is termed as temperature assisted pulsed laser deposition
(TAPLD). Laser vaporization of solid target material and collection of debris on the ultra cold
substrate through condensation process is also well known approach and known as Laser
vaporization controlled condensation (LVCC). Laser Chemical Vapour Deposition (LCVD)
and Laser Pyrolysis are also well established approaches, where laser is used for
decomposition of chemical precursors.
Laser ablation in liquid media is other quick, one step, green and highly emerging
approach and produces highly colloidal solution of nanoparticles for biological applications.
Metal, metal oxide, semiconductor and organic materials can be synthesized too easily using this technique. Various approaches of laser induced nanostructuring and nano-pattering can create nanostructures at the selective site of the solid surface, with applicability for device fabrication and have the potential to validate Moore’s law in future.
This special issue is devoted to the various nanomaterials based on laser processing,
including synthesis, modification and applications. Contributions, such as original research
articles, communications, comprehensive or brief review articles, are especially
solicitated but not limited to the following fields:

(A) Nanomaterials by laser ablation in vacuum and gas
(B) Nanomaterials by laser ablation in liquid medium
(C) Nanomaterials by laser chemical vapour deposition
(D) Nanomaterials by laser pyrolysis
(E) Nanomaterials by other laser processing
(F) Nanomaterial modification by Laser-induced size reduction and reshaping
(G) Nanomaterial patterning by Laser processing
(H) Properties and applications of nanomaterials by laser processing
