Hey guys, im Frank, completely new to LPF, been enjoying lasers casually for a little while and just made my first "real" purchase from Lazerer.
So I purchased the "Mini" 150mw 532nm green laser and it uses a 16340 battery. The one that came with it is an ultrafire 880mah 3.7v. I ordered a power certificate and the laser's stable output is supposedly 150mw, it lights matches and burns through electrical tape. However, my question is this: How come when the battery is fully charged, the laser mode hops out of TEM00? At a sub 50% battery charge the laser operates in TEM00 until the battery dies. At above 50%, the only way I can consistently keep it from mode hopping is by cooling it off in my freezer for about 30 seconds before turning it on. I live in hot south florida so our usual temperature for this year is about 75-80F and its hard for me to keep it in TEM00 when outside. I dont really know much about how the voltage of the battery affects the laser, but it says its a 4.2v on a full charge and 2.7v on an empty charge. Could this have any significance to the mode hop?
Basically I'm just looking for an answer on if I should get a new, more reliable battery or could it just be my laser prefers cooler temperatures?
Thanks for reading
