Raman Interaction
Generation of Raman sidebands in diamond. Two Gaussian laser beams, pump (purple) and Stokes (dark orange), enter a Raman medium (diamond) and generate a broadband of higher order anti-Stokes. The photo was taken with a Canon EOS 80D, by moving a white screen in front of the beams at a 30-second time exposure. The experimental setup was made by Aysan Bahari from Alexei Sokolov's group at Texas A&M University, USA, and the photo was taken by Aysan Bahari and Dustin Scriven, also at Texas A&M. [Honorable mention, 2019 After Image photo contest.]
