Non-photochemical laser-induced nucleation (NPLIN) is the formation of a new phase from a metastable phase by the action of light on matter. Using millijoule, nanosecond laser pulses at visible and near-infrared wavelengths, it is possible to form the new phase localized in the volume of the by: 3.
Laser-induced nucleation is an attractive technique, but the mechanism is not completely understood awa et al. reported that morphological changes in protein solution produced by a femtosecond laser are key factors for nucleation and observed, using fluorescent-labeled lysozyme “in agarose gel”, that laser-induced cavitation bubbles cause an Cited by: ultrasound.1–3 Laser-induced nucleation is a relatively unexplored technique that offers advantages to localizing—temporally and spatially—the point of nucleation.4,5 Such control opens up avenues, e.g., to study of the dynamics of nucleation or to control product homogeneity during manufacture of by: 5.
An overpotential‐free Li nucleation process is identified at current densities lower than mA cm −2. Theoretical computations reveal that the defects serve as nucleation centers during the heterogeneous nucleation of lithium.

Abstract. The formation of positively charged clusters consisting of 10 11 –10 12 molecules and 10 2 –10 4 unit charges has been observed in mixtures of triophenol vapor with a buffer gas when irradiated by a single 30 ns UV laser pulse.
The results indicate a means of controlling the size and the charge of the micron size clusters formed, by varying certain parameters such as the laser. Various mechanisms have been proposed to explain the nonphotochemical laser-induced nucleation (NPLIN). Identifying the dominant mechanism requires addressing a large set of experimental parameters with a statistically significant number of samples, forced by the stochastic nature of nucleation.
In this study, with aqueous KCl system, we focus on the nucleation. with an avalanche-like onset of spontaneous nucle-ation of the entire high temperature liquid layer at about Tc. Therefore, at a temperature of about Tc, homogeneous nucleation, or explosive phase transformation occurs.
During pulsed excimer laser heating, radiation energy from the laser beam is transformed to thermal. A solid-state laser is a laser that uses solid as a laser medium.
In these lasers, glass or crystalline materials are used. Ions are introduced as impurities into host material which can be a glass or crystalline. The process of adding impurities to the substance is called doping. Rare earth elements such as cerium (Ce), erbium (Eu), terbium.
