Coherent radiation emitted by *all* cells is not physically possible.
This would require a population inversion where many structures (molecules, or
parts of molecules) have several eV--tens of kcal/mole--of energy. Furthermore
the pathlength required for lasing and the repeated passage of the reflected
light through the cell cannot happen for most cells. There *may* be a special-
ized cell with enough antennae to lase once, but that is the most that can be
expected. Of course, if there is a new theory of stimulated emission, this
argument might fail, but "biphotonic radiation" by cells sounds like pseudo-
science or worse to me.
