element14 presents's video: How Laser Diodes Work - The Learning Circuit

In this The Learning Circuit lesson, Karen teaches about laser diodes. She begins by explaining how a standard PN diode works. However, laser diodes are PIN diodes. Understanding the I, which stands for “intrinsic” layer, is important to understanding what makes laser diodes different, and how they are able to produce such a small, focused beam. Since laser diodes can be dangerous, Karen reviews laser safety, then wraps up the video by showing off some of the many uses for laser diodes. Keep your eyes peeled for the next video from The Learning Circuit where Karen shows how to use a laser diode to make a trip wire alarm! http://bit.ly/3nJP5tU Engage with the element14 presents team on the element14 Community - suggest builds, find project files and behind the scenes video: http://bit.ly/2MFMG0v Visit the element14 Community for more great activities and free hardware: Tech spotlights: http://bit.ly/2KLz0TS Roadtest and Reviews: http://bit.ly/2KH4fj3 Project14: http://bit.ly/2wPnajx
