When a specific wavelength of laser light is shone on them these vibrations alter the reflective properties of the material, modulating the light bouncing off them.

当某一特定波长的激光照射声纤时，纤维震动便会改变材料的反射特性，并调节反射的激光。

When the strain is removed, it forms a ripply surface, and the spacing of the ripples affects the colour of the laser light, which varies as the material is stretched.

当这种材料的表面产生张力时，就会产生类波纹状的表面，并且这改变还会影响激光器发出的颜色，并且会随着张力的改变而变色。

The Chemistry and Camera instrument, seen above before a recent test firing at Los Alamos National Lab in New Mexico, USES a pulsed laser beam to vaporize a pinhead-size piece of material.

Otherwise, it can be bathed in a liquified form of the second material until all of the voids created by the laser are filled in.

And as the decayed material has an extremely high water content Mr Hansen said that most of the laser's energy is absorbed by the infected tissue, which is then vaporised.

But further measurements using a laser and looking for reflections showed that much of the ice is covered with a layer of dark material tens of centimetres thick.
