In this paper, the mechanical properties of polyimide film under the synergistic effect of electron, proton and near ultraviolet was tested by the space integrated irradiation test facility in Beijing Institute of Spacecraft Environment Engineering, and the tensile strength and rupture elongation of it was studied. Under the synergistic effect of ultraviolet, electron and proton, the mechanical properties decrease in the early stage of irradiation larger than in the electron and proton irradiation, but less than in the degradation of mechanical properties caused by electrons and protons in the later stage of irradiation. During the initial stage of synergistic irradiation of electron, proton and near ultraviolet, the degradation law of mechanical properties of polyimide films is basically consistent with that under electron or proton irradiation. But its tensile strength and rupture elongation will exponentially increase with space combined radiation until tend to stable.","PeriodicalId":197837,"journal":{"name":"SPIE/SIOM Pacific Rim Laser Damage","volume":"211 S663","pages":"129820S - 129820S-5"},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139165597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, fused silica optics were plated with different configurations design (with a duty cycle of 5.5%) of Au-based metal grids, and the light-field distribution and light transmittance of fused silica were simulated as well as the temperature testing was carried out. The results show that the metal grids configuration has marginal effect on the light field intensity, since the Au-based grids with the duty cycle of 5.5% make Light Intensification Factor (LIF) remain constant at 2.95 regardless of its linewidth and period. But the occurrence probability of maximum electric/light field is increased when increasing the linewidth of metal grid, indicating that wider grid has no benefit the light modulation substrates.

Maximizing the energy-loading capability of gratings is a worldwide challenge in the high-peak-power laser field. Here, for 10’s femtosecond-PW pulse compression, an ultra-broadband gold grating was developed to dramatically broaden the high diffraction efficiency bandwidth from 100–200 nm to 400 nm. Moreover, a core mechanism was elucidated whereby the high diffraction efficiency combined with the deep penetration effect of electrons under high-energy laser irradiation can tap the LIDT potential of metal grating. Accordingly, the mixed metal grating was invented and demonstrated experimentally with superior performance in terms of diffraction efficiency bandwidth and LIDT compared with normal gold gratings. In addition, for picosecond-PW pulse compression, a multilayer dielectric grating (MDG) design paradigm was proposed. Importantly, TM-polarized MDGs had the superiority of a high LIDT owing to the low electric field intensity. Furthermore, a novel grating with a LIDT 3.5 times higher than the conventional gratings installed in NIF-ARC and SG-II was obtained by taking advantage of TM polarization and a small incident angle. These results make a pioneering technical reserve to facilitate future 100 PW-class ultrafast laser systems.","PeriodicalId":197837,"journal":{"name":"SPIE/SIOM Pacific Rim Laser Damage","volume":"46 5","pages":"1298202 - 1298202-7"},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139164307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laser-induced damage threshold (LIDT) of fused silica is a key problem that limits the improvement of optical systems. Atmospheric pressure plasma processing (APPP) has great promise for improving LIDT because it involves lowcost, non-contact, and high-efficiency material removal based on its pure chemical etching mechanism. However, the deteriorated surface morphology after atmospheric plasma etching limits the further improvement of LIDT of fused silica. This study analyzes the exposure and passivation processes of subsurface scratches during atmospheric pressure plasma processing. The evolution process of interfacial contours related to the etching and deposition process is described. At the end, a series of etching experiments under different dwell times are carried out and a flexible medium polishing processing is used to improve the deteriorated surface quality. The results indicate that the LIDT of fused silica is significantly increased from 8.1 J/cm2 to 30.8 J/cm2 by APPP and flexible medium polishing processing. APPP is expected to be effective in improving the LIDT of fused silica.","PeriodicalId":197837,"journal":{"name":"SPIE/SIOM Pacific Rim Laser Damage","volume":"13 4","pages":"129820B - 129820B-6"},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139164541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the plasma is usually generated by ionizing gas through the electric field, the charged reactive species are accelerated to bombard the surface when passing through the surface sheath. After the organic contaminants on the surface of the optical components are completely removed, the surface film of the optical components may be eroded by long-time plasma irradiation. Therefore, the surface damage characteristics induced by plasma cleaning on optical components were studied to apply the technology of plasma in situ cleaning in the inertial confinement fusion facilities. Firstly, the effect of the amount of organic contaminants on the performance of optical components was investigated. Then, the influence of plasma cleaning time on the transmittance and wavelength peak of fused quartz optical components coated with sol-gel anti-reflection film was analyzed. The plasma cleaning experiments illustrated that the film thickness had a damage accumulation effect after the long plasma irradiation, and the surface pores gradually increased. The surface damage mechanism of plasma action was discussed. Finally, the research on the surface damage mechanism of sol-gel anti-reflective film during plasma cleaning lays a foundation for the realization of nondestructive in situ cleaning of optical components.","PeriodicalId":197837,"journal":{"name":"SPIE/SIOM Pacific Rim Laser Damage","volume":"107 3‐5","pages":"129820C - 129820C-7"},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139165905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transparent optical elements under the action of strong laser light are prone to produce plasma and even then cause damage to the elements. Therefore, it is important to study the process of interaction between transparent optical elements and strong laser light and its results. In this paper, a theoretical research and simulation study is conducted to investigate the characteristics of pulsed laser induced plasma generation in transparent optical elements represented by fused silica. It is demonstrated that the plasma propagation velocity and the temperature of each part increase with the increase of laser energy density during the interaction between the pulsed laser and the transparent optical elements. The plasma propagation velocity tends to increase and then decrease with the increasing of laser action time, and the temperature continues to increase near the threshold value. The plasma propagation velocity increases with the increasing of laser pulse width, and the velocity variation pattern is similar in all pulse widths. The temperature increases with the increasing of laser pulse width and approaches the temperature threshold that can be reached by the combustion wave generated by the interaction between the pulsed laser and fused silica. Finally, the kinetic characteristics and temperature rise phenomenon of the plasma propagation generated during the interaction between the pulsed laser and the transparent optical element are explained.","PeriodicalId":197837,"journal":{"name":"SPIE/SIOM Pacific Rim Laser Damage","volume":"120 9","pages":"129820F - 129820F-10"},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139163524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The laser damage test for EUV femtosecond pulses was executed at domestic soft x-ray free-electron laser facility in Shanghai. The EUV central wavelength is 13.5 nm and pulse duration is 300 fs. To understand the influence of absorption distribution in the Mo/Si multilayers, the sample was irradiated at normal incident angle for no reflection status. The damage morphologies were characterized by SEM and TEM. It is found that the most severe absorption area appears bubble-like damage, in which the first ten pairs of Mo/Si bilayer merged thoroughly and the bubble under the multilayers is located at the interface close to the substrate. The absorption distribution in the multilayers was simulated by Monto Carlo method, and that was compared with the electric field distribution simulation. We can conclude from the simulation that the damage locations are consistent with the high absorption layers in the coating stacks.","PeriodicalId":197837,"journal":{"name":"SPIE/SIOM Pacific Rim Laser Damage","volume":"24 4","pages":"129820U - 129820U-5"},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139165270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
