This discussion centers on the challenges of stabilizing light beams akin to lasers. It establishes that light consists of multiple frequencies, which complicates the alignment of photons when passing through lenses. High-quality lenses utilize multiple coatings to attempt uniform bending of frequencies, but perfection is unattainable. While achieving laser-like alignment in free space is impossible, techniques for collimating light exist, allowing for effective transport through light pipes or optical fibers.
PREREQUISITESOptical engineers, physicists, and anyone interested in the manipulation of light for applications in lasers and fiber optics.
Godspanther said:It is fairly common knowledge that you can use a magnifying glass to bend light and that at the point where the beam is tightest you can produce great heat. Yet beyond this point the beam scatters as the photons continue to travel on at the same angle at which they left the lense. Is there a way to stabilize the beam like a laser, keeping all the photons traveling in the same direction?
