| 中文摘要 | thermal boat evaporation was employed to prepare mgf2 single-layer coatings upon both jgs1 and ubk7 substrates at different substrate temperatures. microstructure, transmittance and residual stress of these coatings were measured by x-ray diffraction, spectrophotometer, and optical interferometer, respectively. measurement of laser induced damage threshold (lidt) of the samples was performed at 355 nm, 8 ns pulses. the results showed that high substrate temperature was beneficial to crystallization of the film. above 244 degrees c, the refractive index increased gradually with the substrate temperature rising. whereas, it was exceptional at 210 degrees c that the refractive index was higher than those deposited at 244 and 277 degrees c. the tensile residual stresses were exhibited in all mgf2 films, but not well correlated with the substrate temperature. in addition, the stresses were comparatively smaller upon jgs1 substrates. a tendency could be seen that the lidts reached the highest values at about 244 degrees c, and the films upon jgs1 had higher lidts than those upon ubk7 substrates at the same temperature. meanwhile, the damage morphologies showed that the laser damage of the coating resulted from an absorbing center at the film-substrate interface. the features of the damages were displayed by an absorbing center dominated model. furthermore, the reason of the difference in lidt values was discussed in detail.
