We
consider the family of nonlinear Schroedinger equation, which arise from the
study of the nonlinear wave propagation in dispersive and inhomogeneous media.
These equations arise in a wide range of plasma phenomena, in nonlinear and
non-uniform dielectric medium, and in other fields of physics. Using the
Darboux-Bargmann technique, we obtain the Backlund transformations for
nonlinear Schrodinger equation solvable by the inverse-Scattering method and
construct explicit solution and the BT technique is used to generate a new
solution of NLSE from a known solution of the equation. Reference 1-H.Chen and C.S.Liu, Soliton in
