Long-lasting antifogging mechanism for large-aperture optical surface in low-pressure air plasma in-situ treated

Influence of reactive oxygen species concentration and ambient temperature on the evolution of chemical bonds during plasma cleaning: a molecular dynamics simulation

“…The mean square displacement (MSD) represents the statistical deviation of the particle position relative to the reference position after moving over time, which can be applied to describe the mobility of the reactive species. 13 The higher the probability of collision and reaction between the reactive species and organic contaminants. The mobility ability of atomic oxygen and ozone is much higher than that of the hydroxyl radical during the chemical reaction, which may be one reason for the stronger cleaning ability of atomic oxygen and ozone.…”

“…[6][7][8][9] Plasma cleaning, as a precision cleaning method, has a broad application in the pretreatment of materials bonding, printing, painting, coating, and etching, complementing conventional cleaning methods. [10][11][12][13][14] Plasma cleaning has the advantages of high efficiency, environmental friendliness, no secondary contamination, low process cost, and can achieve large area in situ cleaning. 4,15 The plasma can also modify the physicochemical nature of surfaces while cleaning surfaces, enhancing surface adhesion strength.…”

Spatial sputtering of fused silica after a laser-induced exploding caused by a 355 nm nd: YAG laser

“…Plenty of research has been conducted in this area, and academics generally believe that the generation of laserinduced debris is mainly related to the laser beam and the base it has affected. It has reached a consensus that the output of debris is exponential to the incident fluence when the base material and its surface roughness are identical [8][9][10][11], and the debris sputtering behaves varied with different materials and surface roughness, even though the incident fluence remains the same [12,13].…”

“…These propagation forms will result in different interactions between debris and optical components surfaces, and introduce various damage. Hence, online cleaning and protection strategies should be developed accordingly, such as applying plasma to thoroughly blow away scattered adsorption on the optics surfaces [9,17], and dual dynamic airflow to block high-speed impacts on the system [14].…”

Light Absorption Enhancement and Laser-Induced Damage Ability Improvement of Aluminum Alloy 6061 with Non-Porous Alumina/CdSe@Al2O3/SiO2 Functional Gradient Films

“…As part of the PEARL-X facility in Russia, there is a next-generation Perwatt laser facility. In China, an ultra-high-power laser facility at the Shanghai Institute of Optics and Mechanics also has world-leading equipment [ 6 , 7 ].…”
