Is it possible to directly pump a laser using sunlight?
Answers
I have read on wikipedia the basic theory behind laser. A photon passes through an excited electron which then produces the exact same photon. Light is bounced off mirrors to create more photons.
Is it possible to make sunlight passes through an optical amplifier to create a amplified sun light stream ?
Ideally the solution could be use with a simple machine that produces laser but instead takes external light as an input. The application would be to put sunlight into an optical fiber and amplify the number of photons using the technique above.
They already exist. "Solar-pumped lasers already exist: they work by concentrating sunlight onto crystalline materials such as neodymium-doped yttrium aluminium garnet, causing them to emit laser light." (source) They have been innovated though, so there are more efficient method to make solar-powered lasers now.
Hope this helps/....
