I have a RPL-225, 245mw green laser. When I shine the beam close to the corner of a wall but not hitting the wall I see a radial pattern around the main beam on the wall. In this pattern there are light and darker areas. What is unusual(to me) is a small area that comes on and off in green of course. And there are flickers here and there. The laser makes a perfect beam and is too bright to look at reflected so I never noticed this area around the beam.
What is this and why does it happen?
