I looked up a lot of videos for lasers, and this is the cleanest and clearest of them so far. Great video! Covers the basics concisely!

Hello Sir, I am Laser Instructor in Beauty School and last part of your video is what I tell students to write down so they understand how lasers work. They don’t need anything more to remember. Thank you! You make it easy to understand!

My 4yr old son asked me, “why is a laser called a laser?” I said, “let’s find out!” and here we are! Thank you for your video! We really enjoyed it! ❤

Finally someone start to explain first and then Mathematically, this is how I liked and learn in my engineering time, today a lot of Academic start with Mathematics first, but can’t used without understanding why I need this Math and what I like to calculate, in this way makes more sense and the trick is done. Good Job, definitely I subscribe
