Laser-Induced-Electro-Explosion Synthesis of Powder Materials (LIEES)

The temperature characteristics of plasma induced by femtosecond laser radiation

“…As shown in [1,2], energy transported along an electric arc is used to increase the efficiency of obtaining nanoparticles upon ablation from the surface under the influence of laser radiation. In this case, an effective correction of the electric arc can be carried out using optical discharge (OD).…”

Formation of powder materials under the combined influence of pulse laser radiation and electric arc discharge

“…Figure 1 shows the scheme of experimental setup. The paper presents the surface treatment of titanium (11) by the combined action of ultrashort laser pulses and electric arc discharge (6) [4]. The optimal focal length of the optical system (2) was determined to form a region of laser-induced plasma in the caustic region of the required length.…”

“…The high-voltage pulse was formed by the generator (12), the voltage varied in the range from 20 to 30 kV, the energy in the pulse of the electric arc was 0.05-0.1 j. the transition of the arc was carried out from the positive electrode (5) to the negative electrode-sample (11). The process was recorded by CCD camera (4).…”
