Reflecting Gravitons: The Graviton Laser and the Gertsenshtein effect

M. B. Paranjape, Thomas Forget, Urjit Yajnik

Gravitons can be reflected by converting them to photons and back in magnetic fields, enabling a laboratory graviton laser.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We may convert the gravitons to photons, then reflect the photons, then reconvert the photons into gravitons via the same effect, and then pass them through the graviton lasing medium. With an identical apparatus on the other side, we can essentially extend the path length of the gravitons through the lasing medium as arbitrarily long as desired.

C2weakest assumption

That the Gertsenshtein conversion efficiency in laboratory magnetic fields is high enough to overcome losses and produce net gain when combined with a suitable lasing medium.

C3one line summary

Gravitons can be reflected using the Gertsenshtein effect to convert them to photons and back, enabling repeated passes through a graviton lasing medium for terrestrial graviton lasers.
