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 ? ume 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 ?
