We have made an analysis about the different class of soliton and soliton like exact solutions of nonlinear Schrodinger equation in three dimension through the help of a modified Lax pair suggested by Melnikoff. We show that it is possible to generate a new class of solutions which incorporates the usual soliton solutions as special cases. One important and distinctive feature of our calculation is that the input Kernels of the Gelfand-Levitan equation take into account of nontrivial, specified functional form of the boundary conditions of the two dimensional nonlinear field u(x, y) and v(x, y) in both cases of x and y → ∞.
