Femtosecond laser ablation of TiO2 films for two-dimensional photonic crystals

Surface topography to reflectivity mapping in two-dimensional photonic crystals designed in germanium

“…doped), were performed by a Direct laser writing (DLW) using ultrafast lasers wo dimensions [29][30][31]. The optical source for fabrication the periodic structure was a femtosecond regenerative repetition rate, length, and maximum laser energy of about plate placed in front which allows precise attenuation of the laser was focused on the sample by a Mitutoyo microscope objective with high , providing a focused spot diameter of the optimal laser processing parameters, such as processing by mapping, at different laser energies and number of 5 ߤ݉).…”

Dependence of Laser Ablation Produced Gold Nanoparticles Characteristics on the Fluence of Laser Pulse

“…In contrast to chemical nanofabrication methods, laser ablation can be performed in a clean, well-controlled environment, such as deionized water, giving rise to the production of ultrapure nanomaterials. The use of these particles decreases toxicity risks, which is especially important in vivo bio sensing and imaging applications [4][5][6][7][8].…”

Communication—Formation of Porous Anodic TiO2with Square Nanoholes by Pretexturing Process

“…6,7 There have been a large number of reports on the fabrication of nanohole array structures of TiO 2 based on various fabrication processes. [7][8][9][10][11][12] Among them, the anodic oxidation of Ti in an electrolyte containing fluoride ions is a useful process for forming nanohole arrays with high aspect ratios. [10][11][12] The degree of ordering of hole arrays of anodic porous TiO 2 is dependent on the anodization conditions.…”
