Removal mechanism of cleaning surface organic contaminants on SiO2 sol-gel antireflection film by air low-pressure plasma
On demand starting 12 October 2021
The problem of on-line removal of surface organic contaminants of large-aperture optical component in high energy laser systems has not been solved. In this work, an air low-pressure on-line plasma cleaning technique is proposed, which can remove organic contaminants and activate the surface of large-aperture optical component (430mm*430mm ). After air plasma cleaning, the transmittance and damage threshold are restored completely, and the damage of surface structure on optical components are not found. The interaction between air plasma species and organic contaminants was simulated by molecular dynamics to explain the mechanism of removing organic contaminants by air low-pressure plasma.
