How Laser Diodes Work -- The Learning Circuit 83

How Laser Diodes Work

The Learning Circuit | element14 presents | Project Videos

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!

Nice presentation. I had a friend that worked with VCSEL designs about 15 years ago. I've been using quite a few infrared VCSELs lately with the integrated microLIDAR ToF sensors.
