“…Typically, UV excimer lasers operated at either 193 or 248 nm are used in combination with Q-switched Nd:YAG lasers operated at 355 or 532 nm to grow ferromagnetic NiMnSb [103], Al doped ZnO [104], Au doped TiO2 [105,106], and Au doped NiO thin films [107]. Double pulses were also used in reactive pulsed laser deposition where an improved quality of deposited carbon nitride films was obtained for an optimized interpulse delay [108].…”

The purpose of this chapter is to give a critical review of the processes involved in the generation of nanoparticles by material ablation with two time-delayed laser pulses. Experimental investigations of the ablation characteristics during nanoparticle synthesis with short double pulses are presented. In particular, the composition and the expansion dynamics of the ablated material are examined. The latest progress achieved in modeling laser-matter interactions in double pulse regime is discussed. The correlation between ablation efficiency and nanoparticle generation is assessed and compared with numerical simulations, the influence of interpulse delay on metals ablation being revealed.

Abstract:The results of an in-situ plume-laser interaction measurement during welding of mild steel with a 5 kW ytterbium fiber laser are reported. A measurement of the attenuation of probe laser beam passing through the plume has allowed to estimate the plume characteristics like the size of the extinction area and the spatial distribution of the extinction coefficient. The power loss of the fiber laser radiation propagating through the whole plume length was calculated. Together with a measured temporal characteristics of extinction the result indicates a significant decreasing of the laser radiation stability, which can lead to the formation of the macroscopic welding defects. Verification of the extinction coefficient distribution model with experimental data of the extinction signal depending on the plume height

“…urrently, double-pulse lasers are widely used and researched for elemental analysis in laser-induced breakdown spectroscopy (LIBS), precision processing in laser drilling, thin film preparation in pulsed laser deposition (PLD), and lithography machines in extremeultraviolet (EUV) light sources, among other fields. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] The double-pulse LIBS configuration has been shown to significantly enhance the signal intensity of up to two orders of magnitude greater than a conventional single-pulse LIBS. 2) In double-pulse LIBS, the inter-pulse delay and the ratio of the laser pulse energies play an important role, as they directly influence the laser-target interaction and plasma reheating processes.…”

This letter introduces the collinear double-pulse generation method of the electro-optical Q-switched Nd:YAG laser and the rate equations describing its pulse formation dynamics. The two pulses share the same resonator and thus have a natural and highly coaxial characteristic. The effect of the voltage applied on the electro-optic crystal on the pulse energy and temporal waveform was studied. The time interval of the double-pulse laser can be tuned from 80 ns to 10 μs, thus satisfying the needs of a general double-pulse laser. This method is ideal for obtaining a collinear double-pulse laser and can be extended to other lasers.
