Photon Lifetime Explained

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 go over the photon lifetime inside a laser (fabry-perot cavity). This is the first step in formulating a differential equation that will eventually tell us the number of photons inside the cavity, and the output power we can expect from a LASER or LED.

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.
