Laser effects based optimal laser parameter identifications for paint removal from metal substrate at 1064 nm: a multi-pulse model
TL;DR: In this article, the underlying mechanisms and optimal conditions for paint removal by laser ablation are thoroughly investigated on the basis of ablation morphologies and combining experiments with numerical modeling, and the authors suggest that laser paint removal is dominated by the laser vaporization effect, thermal stress effect and laser plasma effect.

Jinghua Han,Qiuhui Zhang,Weixing Fan,Guoying Feng,Yaguo Li,Aixiang Wei,Ruifeng Hu,Qiongqiong Gu +7 more
TL;DR: In this article, the characteristics of Ta2O5 films deposited by radio frequency pure oxygen ion assisted deposition (RFOIAD) technology were compared to a gas mixture of oxygen and argon (O2/Ar) ion beam assisted deposition experimentally and theoretically, including of optical, electronic, and laser-induced damage resistance.

Thermodynamic damage mechanism of Ni/Cr film on neutral density filter by 1064-nm pulsed laser
TL;DR: In this article, the authors investigate the damage characteristics and mechanism of neutral density filters consisting of metal film on K9 glass substrate by 1064-nm pulsed laser and show that the difference between the thermodynamic properties of impurities and film can lead to thermos-elastic stress, which plays important roles in deformation of film, nucleation and propagation of cracks.
