Laser ablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam.

The narrow beam width of a normal parabolic satellite antenna means it can only receive signals from a single satellite at a time.

Light sources There are many sources of light.

A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning it with a focused beam of electrons.
