“…However, in some works, double-pulses trains with the same wavelength are being used for the ripple formation 28,29 and also for laser micro-fabrication [30][31][32][33] . In the more complicated approaches, the dual-wavelength double-pulse trains with the time delay in between pulses have been used for various laser processing experiments [34][35][36][37][38] . In the last half-decade, much research on the ripple formation upon the double-pulse femtosecond laser irradiation on silicon and fused silica has been done using parallel- [39][40][41][42][43] and crossed-polarizations [44][45][46] .…”

“…Furthermore, the utilization of hybrid optimization algorithms has been observed in the field of additive manufacturing, particularly in the context of laser-based techniques such as selective laser melting (SLM), which are employed to fabricate complex threedimensional structures. Researchers achieved the optimization of SLM parameters by integrating genetic algorithms with AI-driven simulations [167][168][169][170][171]. This approach resulted in the creation of components that exhibit superior structural integrity, exceptional surface polish, and reduced residual stresses.…”

Laser Beam Machining (LBM) has several applications in the aerospace, medical, and automobile domains. Optimization techniques are essential for LBM to increase resource-efficiency and sustainability of the system. The present paper aims to provide a systematic review of the research in the domain of optimization techniques for LBM. A total of 228 research papers published during the last 20 years, from 2003 to 2023, are reviewed. The literature review is classified into three major sections- (i) optimization techniques, (ii) applications of optimization techniques, and (iii) challenges and future directions. The novelty of the present systematic review paper is to provide a direction for future research in the domain of optimization techniques of LBM. As a result of the suggested research, an efficient and sustainable LBM with the required performance will be developed in the shortest possible time.

“…There are a number of evidences indicating that ultrashort-laser-based technologies can be substantially improved by using combinations of different wavelengths with higher efficiency and better quality of material processing and nanoparticle generation. Thus, combining infrared and visible laser pulses has been demonstrated to allow for enhancing the ablation efficiency of materials with improved crater morphology [1][2][3][4]. The use of bi-chromatic femtosecond pulses can improve the quality of laser-processed surfaces [5], provide control over properties of laser-induced periodic surface structures [6][7][8], enhance the efficiency of laser energy coupling [4,9] and nanoparticle synthesis [10], and increase the kinetic energy of laser-generated photoelectrons [11].…”

A study of damage and ablation of silicon induced by two individual femtosecond laser pulses of different wavelengths, 1030 and 515 nm, is performed to address the physical mechanisms of dual-wavelength ablation and reveal possibilities for increasing the ablation efficiency. The produced ablation craters and damaged areas are analyzed as a function of time separation between the pulses and are compared with monochromatic pulses of the same total energy. Particular attention is given to low-fluence irradiation regimes when the energy densities in each pulse are below the ablation threshold and thus no shielding of the subsequent pulse by the ablation products occurs. The sequence order of pulses is demonstrated to be essential in bi-color ablation with higher material removal rates when a shorter-wavelength pulse arrives first at the surface. At long delays of 30-100 ps, the dual-wavelength ablation is found to be particularly strong with the formation of deep smooth craters. This is explained by the expansion of a hot liquid layer produced by the first pulse with a drastic decrease in the surface reflectivity at this timescale. The results provide insight into the processes of dual-wavelength laser ablation offering a better control of the energy deposition into material.
