DIY front surface mirrors 2
can you trap a beam of light?
If you had a two way mirror and a regular mirror both with absolutely flawless 100% reflective surfaces and you shined a bright or laser light through the two way into the regular mirror, would you be able to trap the beam of light between the two reflective surfaces once the light source was removed ? assume that the light and mirrors could be perfectly aligned and that the reflective surfaces are flawless and shaped to keep the light from reflecting off at an angle. do we know enough about the nature of light to say for sure that this would or would not create a permanent light source ?
You have described what is known in optical physics as a Fabry-Perot cavity. The parameter you are interested in is referred to as the cavity lifetime (how long the light will remain in the cavity). A related parameter is the finesse and can be thought of as the average number of round-trips the light makes before exiting the cavity (in your case, through the two-way mirror). The finesse is related to the how lossy the mirror is. The higher the reflectivity of two-way mirror, the longer the cavity lifetime will be. Unfortunately, the higher its reflectivity it will also be harder to put much light into the cavity (this is fundamental to the way partially reflecting mirrors work). In the end you will run into a situation where you have a trade-off between the length of time the light will remain in the cavity and the amount of light in the cavity. That means, you can only have a cavity with an infinite lifetime if no light can get in. Even if you were to somehow get the light into the cavity it could not get out.
