Do you think my plan for a homemade laser will work? PLEASE RESPOND SO I CAN IMPROVE MY PLAN.
Lately, I've been thinking. When school starts, I will be in 8th grade which means that will be the year when my class get's it's first science fair. I've been studying lasers for the past week and I have found that lasers are actually quite simple. You simply have a light or electrical source energize a gas or solid causing a shift in the electrons in the atoms, thus releasing energy as a photon. The photons released are bounced in a straight line between a fully reflective mirror and a partially reflective lens which allows some light to escape, i.e., laser light. And then the light is focused with concave lenses. Well, my plan simply calls for an electric coil to surround a vacuum tube filled with nothing but Helium and neon. The electricity will travel between the coil and the gas, thus energizing the gas and releasing photons. On one side of the vacuum tube, there would be a simple mirror and on the other, a glass sheet with a slightly white tinge to reflect photons but still allow some to pass through, i.e., laser light. Then, there would be a series of concave lenses with spaces in between them filled with Helium and Neon so that the laser would gain strength as it leaves the source by causing similar reactions in the other gas chambers like in the original diode only not as strong but enough to further strengthen the beam by increasing the number of photons and then focusing them. I don't know how many of you know this much about lasers, but if you see any flaws in my plan, then please tell me so I can modify my schematics.
