| 英文摘要 | Laser-induced damages to tio2 single layers and tio2/sio2 high reflectors at laser wavelength of 1064 nm, 800 run, 532 urn, and pulse width of 12 ns, 220 ps, 50 fs, 8 ns are investigated. all films are prepared by electron beam evaporation. the relations among microstructure, chemical composition, optical properties and laser-induced damage threshold (lidt), have been researched. the dependence of damage mechanism on laser wavelength and pulse width is discussed. it is found that from 1064 nm to 532 nm, lidt is mainly absorption related, which is determined by film's extinction coefficient and stoichiometric defects. the rapid decrease of lidt at 800 nm is due to the pulse width factor. tio2 coatings are mainly thermally by damaged at long pulse (tau >= 220 ps). the damage shows ablation feature at 50 fs.
