A possibility of detecting the effect of photon-axion mixing in a cavity
experiment is discussed. There are two photon-axion modes that acquire
different indices of refraction and split in an inhomogeneous magnetic field.
For a magnetic field inhomogeneous in the direction transverse to the light
propagation an analytical solution is obtained both for the index of refraction
and the beams' trajectories. In a cavity experiment, the beam splitting creates
a bifurcation effect, which results in a decrease of the light intensity in the
central region. Modulation of magnetic field can separate this effect from
background by providing a narrow frequency range for any observed signal. When
one integrates this effect over time and accounts for bandwidth, the overall
drop in FWHM intensity is of order 10-2%. This is a very measurable effect.
