  A broadband quantum echo effect in a three level $\varLambda$-type system
interacting with two laser fields is investigated theoretically. Inspired by
the emerging field of nuclear quantum optics which typically deals with very
narrow resonances, we consider broadband probe pulses that couple to the system
in the presence of an inhomogeneous control field. We show that such a setup
provides an all-electromagnetic-field solution to implement high bandwidth
photon echoes, which are easy to control, store and shape on a short time scale
and therefore may speed up future photonic information processing. The time
compression of the echo signal and possible applications for quantum memories
are discussed.
