Growing Crystals for Laser Second Harmonic Generation (Laser Frequency Doubling) [video]
- peter_d_sherman 3y agoHere's an interesting part of the video: https://www.youtube.com/watch?v=UaslPhb9_ls&t=427s https://www.youtube.com/watch?v=UaslPhb9_ls&t=427s Notice how a little bit later, at the precisely correct angle, the crystals start to emit a huge amount of green light! (https://youtu.be/UaslPhb9_ls?t=451 https://youtu.be/UaslPhb9_ls?t=451) Keep in mind, the energy source for the above visible light is originating from an infrared laser. If that's not a cool phenomena -- then I don't know what is! Related: Les' Lab Channel on YouTube: https://www.youtube.com/@LesLaboratory/videos https://www.youtube.com/@LesLaboratory/videos
