LASER Above Threshold Explained

  / edmundsj  
If you want to see more of these videos, or would like to say thanks for this one, the best way you can do that is by becoming a patron - see the link above :). And a huge thank you to all my existing patrons - you make these videos possible.

In this video, I calculate expressions for the laser output power above threshold, or when stimulated emission is by far the dominant recombination term. I also introduce the notion of threshold gain and threshold current, which we will explore more in future videos.

This is part of my graduate series on optoelectronics / photonics, and is based primarily on Coldren's book on Lasers as well as graduate-level coursework I have taken in the EECS department at UC Berkeley.

Hope you found this video helpful, please post in the comments below anything I can do to improve future videos, or suggestions you have for future videos.
