In this paper, sol-gel single-layer SiO2 anti-reflective coatings modified with PEG were deposited on K9 glass by sol-gel dipping-coating method. The coatings were irradiated by a Q-switched Nd:YAG high power laser whose wavelength was 1 064 nm and pulse width was 3 ns. The microstructure of sol was observed by TEM and the surface morphologies of the coatings were observed by AFM before they were irradiated. The morphologies of the damaged coatings were observed by microscope. Damage mechanics of the laser were studied. The results show that PEG can modify the microstructure of SiO2 coating and thus the induced damage threshold of coating was distinctly improved.
