Abstract
Photon-regeneration experiments which search for the axion, or axionlike particles, may be resonantly enhanced by employing matched Fabry-Perot optical cavities encompassing both the axion production and conversion magnetic field regions. Compared to a simple photon-regeneration experiment, which uses the laser in a single-pass geometry, this technique can result in a gain in rate of order F2, where F is the finesse of the cavities. This gain could feasibly be 10(10 12), corresponding to an improvement in sensitivity in the axion-photon coupling gaγγ of order F1/2∼10(2.5 3), permitting a practical purely laboratory search to probe axion-photon couplings not previously excluded by stellar evolution limits or solar axion searches.
