  Recently, the configuration using atomic interferometers (AIs) had been
suggested for the detection of gravitational waves. A new AI with some
additional laser pulses for implementing large momentum transfer was also put
forward, in order to improve the influence of shot noise and laser frequency
noise. In the paper, we use the sensitivity function to analyze all possible
configurations of the new AI and to distinguish how many momenta are
transferred in a specific configuration. With the analysis for the new
configuration, we explore the detection scheme of gravitational wave further,
in particular, for the amelioration of the laser frequency noise. We find that
the amelioration is definite in such scheme, but novelly, in some cases the
frequency noise can be canceled completely by using a proper data processing
method.
