LASER Cavities - Supported Modes and Mode Spacing

  / 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 talk more about fabry-perot cavities, and include the effects of phase of the electric fields bouncing around in the cavities. The consequence of this is that the cavity only supports very specific wavelengths or 'modes', even when the gain would appear to make our previous expression blow up.

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.
