Shaking molecules until Laser Light comes out. DIY Raman Laser!

Episode 60 #Raman #Laser In this episode, let's build a Raman Laser! First I talk about some of the background of light scattering, Rayleigh Scattering, Raman Scattering discovered by C.V Raman, then the discovery of the Raman Laser by Gisela Eckhardt. I cover the physical setup from an engineering standpoint. An old Nd:YAG Tattoo Laser I refurbished is used to pump a cuvette filled with a Raman Liquid. Although in the early experiments the megawatt Laser energy destroyed the cuvette I was using, I built a Raman cell from scratch, with replaceable windows. Do I manage to shift 532nm green light to 629nm Red? References: Physics openlab: https://physicsopenlab.org/2022/01/11...
