How to normalise a FFT of a 3 variable function.

I have this function:
input = exp(-((W-w_o).^2)/deltaW.^2).*exp(-(Kx.^2+Ky.^2)/(deltaK.^2)).*exp(1i.*sqrt((W/c).^2-(Kx.^2+Ky.^2)).*z(j));
this is then fourier transformed:
fourier = fftn(input)
I need to normalise it. Dividing it by length() is not giving good results. Could someone please help!
