Some green lasers will slowly get brighter and then reach full power. As for the second one, you might need to check connections on the spring and the battery. Mine needs to be cleaned cause it does that too.

It could also be a switch problem.

ALSO, mine acts exactly like your second one when its around 60 degrees F. Even when I clamp it to my table it still does that until it warms up.
If its new, than it might just need to be warmer. Or it could be defective.
