What Is a Laser?

In this interactive activity adapted from NASA, examine the properties and some of the applications of laser light. Through a series of illustrations and animations, you’ll learn how laser light differs from other forms of light, including natural light. You’ll learn how the terms monochromatic, coherent, and collimated describe laser light. Finally, you’ll learn that engineers can regulate laser light to make it suitable for cutting and welding, recording and playing digital media, and even mapping objects in space.

This media asset was adapted from The Space Place: What Is a Laser?/NASA
