The process of concrete damage was simplified by damage parabola model,and uniform damage math model was established,which can precisely predict concrete service life.

Its electrical properties have been well characterized, but there is little report about the laser-induced damage properties of SCS.

Defects in thin film are one of the most important factors influencing laser-induced damage in the thin film components, and always a major concern.

When the elements are used under high power condition, the laser-induced damage threshold will is reduced.

Influence of preparation process on laser induced damage threshold of HfO_2 films;

Laser induced damage threshold(LIDT) was measured and the damage morphologies were plotted by optical profiler.

The real-time results from laser induced damage to samples using photothermal deflection technique support this model.

Recognition of film laser damage based on wavelet transform;

Laser damage threshold measurement of the optical elements;

ZrO_2 is an important material used in high laser damage coatings.

The photodamage threshold of Mg∶Er∶LiNbO_(3) waveguide substrate was tested by m-line method.

The values of photodamage resistance ability of In-doped series LiNbO3 crystals were obtained by the facula distortion method.

The threshold concentration of～3mol% of In for In:Er:LiNbO_3 was confirmed through the measurements of the absorption spectra and the photodamage resistance ability of In(3mol%):Er:LiNbO_3 is over three orders of magnitude higher than that of Er:LiNbO_3.
