Thanks for the useful information.I just bought a green green laser pointer (http://www.freaklasers.com) from LPP.I am testing it now.

There isn't enough info here to understand the problem.
If you're interested in an analytical solution: If the plane wave is coherent with the laser (e.g., same source) it's just a matter of path lengths and wavelength. You'd need to pick one particular point on the sphere or you'll get a distrtibution of path lengths. If the two sources are not coherent but are monochromatic (they have to be), you have a time-varying phase difference.
If you want an experimental setup: You need to project both sources onto a screen with roughly equal intensities so you can see interference fringes. Again, the reflection from a sphere will be a problem because it isn't a point source, so reflection path lengths are continuously distributed over some range. Also, dispersing the laser light to cover an area would introduce the same sort of distribution.
