Short-wavelength, Tiny light spot, Small thermal effect, With obvious advantages when processing the heat sensitive materials.
波长短，聚焦炮点小，热效应小，加工对热源很敏感的材料时紫外激光具备明显的优势。

That is because such systems use high-frequency (and therefore short-wavelength) radio waves that readily bounce off small objects that they encounter.
FIRE FROM THE SKY: This false-color, short-wavelength infrared image of the Eyjafjallajokull volcano's smaller eruption in March shows the power ofthis glacier-covered volcano.
