Light amplification with open-ended laser tube

Click For Summary
SUMMARY

The discussion centers on the feasibility of using an open-ended laser tube designed for light amplification through stimulated emission. Participants explore the concept of photons stimulating each other within the tube, potentially doubling the intensity of the incoming beam. The conversation also touches on the behavior of emitted photons and the implications of using a beam splitter to combine amplified beams, raising questions about interference patterns. The primary focus is on the design and functionality of optical amplifiers in laser technology.

Is it possible to get a laser tube with the ends unmirrored, designed such that a photon being sent through will have a good chance of stimulating another photon to be emitted? If this is possible, then a beam of light going into the tube would be roughly doubled in intensity.

When stimulated emmision occurs, is the stimulated photon physically close to the photon causing the emmision? If so, I would think that if multiple emmisions occurred, the photons would form a sort-of clot as they moved through and exited the tube.

Yes, that's it. Now, if a beam were split using a standard beam-splitter, both paths amplified, then the beams brought back together, would they create interference?
