Hi all
I've got 50mW green laser pointer (from amazon.com). When I put the batteries included, the beam and dot was very bright, but after a minute it's got drastically reduced. From a bright it becomes a very pale dot and non-visible beam. I thought that the batteries are dead, but when I put new ones (alkalines) the problem remains After a break of 10-15 minutes it starts to shine bright again, then after a minute or two- pale. What may be the problem- defect crystal or something?
