“…As the main focus of this review lies on the plasma formation and possible influence of the plasma on the nanoparticle generation and growth, it will be discussed within the next chapter. A discussion on the interaction of nascent plasma with the surface or with the laser beam for gaseous media can be found elsewhere [150][151][152].…”

Laser ablation in liquid-phase (LAL) has been developed since the 1990s, but the interest in laser synthesis of colloids has emerged in the last decade due to a significant improvement in the production rate, proven comparative advantages in biomedical and catalysis applications, and recent commercialization. However, the method relies on highly transient phenomena, so that the fundamental understanding lacks behind the LAL synthesis refinement research. The complexity of the physics and chemistry involved has led to experimental and theoretical investigations that attempt to provide a basic description of the underlying processes but face the challenge of temporal and spatial resolution as well as non-equilibrium conditions. It appears that the processes occurring at the early time scales, ranging from femtoseconds to several microseconds are critical in the definition of the final product. The review is mainly dedicated to the comprehensive description of the processes occurring at early time scales, which include the description of laser-matter interaction for ultrashort and short laser pulses, plasma formation processes as well as comparison of the measured plasma parameters at these time scales, and subsequent description of the cavitation bubble dynamics. Furthermore, the plasma and cavitation bubble chemistry are addressed, and their impact on the nanoparticle formation is emphasized.

“…They deposited high-quality thin film of YBa 2 Cu 3 O 7 which could not have been produced through other alternative techniques. Following this, the PLD technique has been successfully implemented for the manufacturing of thin films with a wide range of properties (ceramic oxides, nitrides, metallic multilayers with high crystallinity) [15][16][17]. One of the most notable advantages of PLD are the lower costs, when compared with molecular beam epitaxy (MBE) or metalorganic chemical vapor deposition (MOCVD), and improved control over stoichiometry, phase and thin film composition.…”

The history of pulsed laser deposition (PLD) and transient plasmas generated by laser ablation is intertwined with the development of various techniques for its fundamental understanding. Some diagnostic tools have been developed to better suit the rapid transient nature of the plasma (space and time dependence of all parameters, fast decay and complex chemistry inside the plasma), whereas others have been adapted from basic plasma physics studies. Langmuir probe method has been used as a real-time in situ diagnostic tool for laser ablation and later for PLD. It remains a useful tool for the PLD community arsenal, which can easily be adapted to the development of new lasers and ablation regimes and new deposition configuration, being one of the most versatile techniques for plasma diagnostics. It is the cornerstone on which charge particles are analyzed and has led to several important discoveries, such as multiple peak distribution, selective acceleration during expansion, plume splitting, plasma turbulences and fluctuations. However, because the Langmuir probe theory adaptation from classical plasma physics is not straightforward, it might lead to misinterpretation and often incorrect analysis of data. This review analyzes the limits and understanding of the technique as a foundation for attaining its full potential, which can impact the way PLD is used. This is especially useful for the pressing need of real-time, in-situ diagnostics and feedback loops for systematic semi-industrial implementation of the PLD technique.

“…Nevertheless, recent computational studies have made significant strides in this area which have allowed us to compare experimental results with numerical simulations. [11][12][13] In this study, a combination of shadowgraphy imaging and in situ nanoparticle characterization has provided the details necessary to perform the requisite comparison.…”

In this work, the effect of laser fluence on Au nanoparticles synthesized via laser ablation in liquids is studied for 1064 nm irradiation with 25 ps pulses. Particle size and polydispersity is found to display a negative trend with fluences up to ∼14 J cm(-2). Erratic size tendencies are observed at low fluences, i.e. slightly above the ablation threshold. This overall behavior is reconciled with recent computational studies and to fluctuations in ablation due to surface morphology. The effectiveness of the commonly used surfactant sodium dodecyl sulfate (SDS) is shown to diminish at higher fluence due to pyrolysis. In addition, shadowgraph imaging of the cavitation bubble is shown as a useful technique for determining the ablation threshold. Our findings are in good agreement with threshold values determined by traditional methods and are comparable to computational values, when differences in pulse duration are taken into account.
