 Intense light pulses that can precisely sculpt solid materials also generate dazzling rainbow patterns that reveal information about the surface. Not just a pretty face. This colorful pattern of light scattered from a solid surface being hit with laser pulses can convey details of the surface damage, such as the size of the laser-generated crater. A spectacular sunburst of colored light produced as a laser beam bores into a solid surface... read more | Read more news
