I'm having some problems with a >1.4W 445nm build. After working perfectly for half an hour, the laser began to flash at a higher output when turned on and then instantly switch to a very low power output. Just now it stopped flashing and is consistently outputting the dim dot. Low as in <5mw.
The two attached photos show a focused and unfocused beam at around 1m from a wall.
It's running on a buck driver at 1.1A and on 2 18350 cells. The cells are protected (though they still measure 3.8V) and although they are cheap, I don't think they can just lower their output by a huge margin instantly.
The diode is a M140 and it runs at a reasonable temperature.
Thanks for any help; I don't want to pester the seller just yet in case it turns out to be a stupid mistake on my part.
