  The bosonic nature of light leads to counter-intuitive bunching effects. We
describe an experimentally testable effect in which a single photon is induced
through a highly reflecting beamsplitter by a large amplitude coherent state,
with probability 1/e in the limit of large coherent state amplitude. We use
this effect to construct a viable implementation of the bare raising operator
on coherent states via conditional measurement, which succeeds with high
probability and fidelity even in the high amplitude limit.
