Spatial non-uniformity is measured by applying a small laser spot scanning across the detector sensitive area.

面响应不均匀性的测量是利用小的激光光斑在探测器的灵敏面进行二维扫描。

This is because they used a small laser spot in the process; it was less than 500 micrometers in diameter — about half the diameter of laser spots used in traditional material deposition.

因为在沉积过程中，他们使用的是直径小于500微米的激光斑点，这大概是传统材料沉积中使用的激光斑点直径的一半左右。

With graphene as a component instead of traditional materials, scientists could develop a laser as small as a pencil that's immune to thermal damage typically caused by intense beams.

He has also made molds for NASA and is working with the U.S. Defense Department to make small parabolic antennae for reflecting laser beams.
