摘要: 为了优化光学薄膜的防护性能,延长使用寿命,本文创新性地采用液态防护膜以保护光学薄膜,制备了三种不同的液态防护膜,包括纯物质防护膜、混合液态防护膜和胶体防护膜。探究三种液态防护膜的透过率、激光损伤阈值(LIDT)和自修复性能,并对液态防护膜的防护效果进行研究。结果表明,三种液态防护膜中胶体防护膜性能最为优异,其中SiO2胶体透过率达91.8%,LIDT达34.2 J/cm2。基于液体可流动的特性,三种液态防护膜都具有一定的自修复性能,能够重复多次地抵御高能激光辐照。在激光辐照下,SiO2胶体防护膜的损伤面积小,自修复时间最短。经过激光损伤阈值测试后发现,装配液态防护膜后的光学薄膜具有更优异的防护效果。

Abstract: In order to optimize the protective performance and extend the service life of optical films, this paper innovatively uses liquid protective films to protect optical films. Pure substance protective films, mixed liquid protective films and colloidal protective films were prepared. Transmittance, laser damage threshold (LIDT) and self-healing properties of three types of liquid protective films were studied. The results show that the colloidal protective films have the best performance among the three liquid protective films. The transmittance of SiO2 colloid reaches 91.8% and LIDT reached 34.2 J/cm2. Based on the fluidity of liquids, all three types of liquid protective films have certain self-healing properties, which can repeatedly resist high-energy laser irradiation. Under the laser irradiation, the damage area of SiO2 colloidal protective film is small and the self-healing time is shortest. After laser damage threshold testing, it is found that the optical film assembled with liquid protective film has better protective effect.

Key words: liquid protective film; transmittance; laser damage threshold; SiO2 colloid; self-healing; laser irradiation
