Controlpulse is coupled into this pulse shaper by wavelength division multiplexer. Nonlinear phase shift of signal laser is induced by controlpulse because of cross phase modulation.
Steering exposure time of a camera through control electron shutter with laser echo pulse is an effective method for inhibiting background noise.
