“…Another fascinating area of research has emerged in PLAL, which involves the introduction of an external environment, such as an electric, magnetic, or temperature field, to examine the behaviour of NPs [160]. External fields have shown a dominant effect on nanostructural formation.…”

Pulsed laser ablation in liquid, used for nanoparticle synthesis from solid bulk metal targets (a top-down approach), has been a hot topic of research in the past few decades. It is a highly efficient and ‘green’ fabrication method for producing pure, stable, non-toxic (ligand-free), colloidal nanoparticles, which is often challenging using traditional chemical methods. Due to the short time scale interaction between the laser pulses and the target, it is difficult to achieve complete control on the physical characteristics of metallic nanoparticles. Laser process parameters, liquid environment, and external fields vastly effect the shape and structure of nanoparticles for targeted applications. Past reviews on pulsed laser ablation have focused extensively on synthesising different materials using this technique but little attention has been given to explaining the dependency aspect of the process parameters in fine-tuning the nanoparticle characteristics. In this study, we reviewed the state of the art literature available on this technique, which can help the scientific community develop a comprehensive understanding with special insights into the laser ablation mechanism. We further examined the importance of these process parameters in improving the ablation rate and productivity and analysed the morphology, size distribution, and structure of the obtained nanoparticles. Finally, the challenges faced in nanoparticle research and prospects are presented.

“…Одной из важных задач нелинейной оптики [1] является изучение процессов, которые связаны с взаимодействием световых полей большой интенсивности с различными материалами [2]. Хорошо известно, что лазерными импульсами можно управлять при помощи сильных внешних полей (магнитных [3], акустических [4], электрических [5]), а также с помощью самой среды, в которой распространяется импульс. Отметим, что в результате взаимодействия со светом изменяются не только исходные свойства вещества [6,7], но и характеристики самого электромагнитного импульса.…”

In this work, we study the interaction of extremely short pulses with a nonlinear anisotropic optical medium with carbon nanotubes (armchair and zigzag type) with metallic conductivity. The dependence of the pulse shape, width, and intensity on the nanotube chirality indices is analyzed. The most appropriate type of carbon nanotubes is substantiated for providing localized propagation of an electromagnetic field in a medium with anisotropic properties.

“…One of the important problems of nonlinear optics [1] is the study of processes that are associated with the interaction of high-intensity light fields with various materials [2]. It is well known that laser pulses can be controlled by strong external fields (magnetic [3], acoustic [4], electric [5]), as well as by the environment, as such, in which the impulse propagates. Note that as a result of interaction with light, not only the initial properties of matter [6,7] change, but also the characteristics of the electromagnetic pulse itself.…”
