Here's the situation:
I purchase this 125mW laser and when I point it to a match (at distance 3 inches), the match will not light.
So I purchase another 75mW from some other company and the match was light at 3 inches away. So either the 125 is underpowered or the 75 was overpowered.
So i changed the batteries to new Energizer e2 alkaline, and point both lasers at a white wall and looked at the dots (I'm wearing 532nm goggles). To my suprise both dots is of identical brightness. (Probably the my goggles has flattened the input).
So I put on a magnifying capset to the 125mW laser. Because the dot is magnified now, I looked at the dot closely and notice a dot like peanut shaped (so not a TEM00 but more like a TEM01 mode).
I've captured a picture taken thru goggles. I've attached the picture together with this message.
Is this considered a laser defect?
