I don't quite understand why people think photons don't leak out of the
Shawyer apparatus.  If you look at a Fabry-Perot resonator - two parallel
mirrors (an etalon).  The reflectivity for each of the mirrors can be
99.999%, and the etalon Q will be quite high, but at the resonance, light
will pass through the etalon with relatively little attenuation.  This is
because the energy inside the resonance is related to Q which is related to
reflectivity.  When the reflectivity is high, the Q is high, so the field
intensity inside the etalon is very high (multiplied by Q).  Then when you
take that internal field intensity and multiply it by the reflectivity,
most of the input comes out (at resonance).
