I noticed something somewhat odd with my 50mw green laser last night. On batteries below 1.4v, when I turn it on it is a single, narrow beam. However, when I use stronger batteries (fresh ones around 1.5v), when I turn it on the beam starts out narrow but then like expands into 2 seperate beams, kinda hard to explain but that is what it does. Everytime it starts as a single tight beam and then expands into 2 seperate beams. Anyone know why this could be or what is causing it? I don't think it affects the power though because about 10 feet away the beam converge again. Anyone have any advice on what can be done to fix this or what the problem is?
Here are 2 photos that illustrate what I am talking about.
Weak batteries below 1.4v, single concentrated beam.
Stronger batteries around 1.55v (fresh), 2 different beams.
