Physics of Laser-Induced Plasma Streams Under Irradiation of Metals with Nanosecond Laser Radiation Pulses at Atmospheric Pressure

“…On the other hand, recent works [19][20][21][22][23][24], because of their narrow practical purposefulness, are characterized by widely disconnected topics, and, therefore, it is very diffi cult to reconstruct on their basis the integral physical picture of the phenomenon under investigation. However, the results of a number of works [25][26][27][28] show that the processes of plasma initiation under the action of high-power nanosecond laser pulses on metals in air can serve as the basis for developing effective technologies of laser treatment, including those aimed at bulk [29][30][31] and surface [32] modifi cation of functional materials by metal nanostructures.…”

“…Nanosized particles formed in the erosion torch of metals can be precipitated into liquid media to form colloidal solutions of corresponding metals [29]. Figure 5 presents the data of investigations of particles precipitated from such colloidal solutions on substrates by the methods of scanning electron microscopy (SEM) and transmission electron microscopy (TEM) [28,30]. It should be noted that proper treatment of such colloidal solutions permits obtaining metal-polymer composite fi lms (Fig.…”
