Thanks for your reply. Quantum mechanics is mostly about energy and time - the amount of energy one needs to transfer and the amount of time required (hence, the uncertainty principle). If it takes longer for photons to find the sink (because they keep getting bounced around) then the preferred...
These are laser transition photons. In a laser, there is initially spontaneous emission of photons and many of these are "lost" in terms of their contribution to the beam. Some are on the main axis of the mirrors and therefore can participate in stimulated emission. The purpose of the mirrors...
Has anybody ever tried adding mirrors around a laser tube cavity where a lot of spontaneous emission can be reflected back into the tube? The idea is like this - if there is a low probablitity of absorption, perhaps the emissions will be induced to occur down the main laser tube where the...
