Multiple Diffracted Beams
This image is made by exciting the pink dye in an hourglass toy with green laser beam (λ = ~532 nm), passed through the pointer's photonic crystal cap, producing multiple diffracted beams. The pink dye can be seen to fluoresce with beautiful golden orange color along the path of diffracted laser beams. Image taken with RedMi Note 7 Pro 48 MB Camera @ RAW mode and processed thereafter. My son Omar Khayyam helped processing the image.
