Femtosecond laser induced phenomena in transparent solid materials: Fundamentals and applications

Nanoscale Phase Separation in Lithium Niobium Silicate Glass by Femtosecond Laser Irradiation

“…No obvious fluctuation in the concentrations of O, Si, and Nb were observed, confirming the SEM/EDS analysis. Alkaline atoms migrate easily under the laser irradiation and so ion beam analyses were performed to determine the Li distribution. Ion beam analysis is a powerful tool to simultaneously investigate concentrations and distributions of different constituent elements.…”

“…Exposure of silica‐based glasses to femtosecond (fs) laser irradiation induces numerous novel phenomena after initial multiphoton absorption . To date, various permanent changes including space charge migration, stress field creation, and crystalline phase transformation have been reported.…”

Proof‐of‐Concept Studies Directed toward the Formation of Metallic Ag Nanostructures from Ag3PO4 Induced by Electron Beam and Femtosecond Laser

“…The interaction of femtosecond (fs) laser radiation with matter has been extensively studied and practically utilized for surface manipulation at the micro‐ and nanoscale levels, having a critical role in material processing at the micro–nanoscale . In this context, Tan et al presented a critical overview of the current state of the art in studying different fs laser–induced phenomena in transparent materials including their physical and chemical mechanisms, applications and limitations, and future research trends. Although, these topics attract significant interest and demonstrate considerable potential for many applications, the phenomenology of these processes is complicated.…”

In-fiber Mach-Zehnder interferometer inscribed with femtosecond laser for high temperature sensing

“…In order to achieve this, low writing speed and repetition rates above 50kHz are required. 4 In this case 120 kHz and 10 µm/s have been selected. Filamentation is produced below focal volume inducing positive index change while focal volume produces a negative index change for this configuration.…”

“…4 Although their application on building In-fiber Mach-Zehnder Interferometers has been widely extended already, they have been limited to open/inner air cavities 2, 3 having its potential to create optical waveguides unused to the best of autor knowledge.…”
