LASER Near Threshold Explained

If you've felt like the content here has been helpful, please consider donating to UCI with a mention of this channel: https://give.uci.edu/ Now we know what a LASER's output power looks like when the stimulation emission is dominant and the spontaneous emission is dominant (in the limits of high and low current), but what does it look like in the middle? And what exactly is the cutoff point between the two? This video explores these questions. 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.
