I got a 1w guardian series 445nm laser from sanwu. I had it running at 15 on and 45 off. It worked great for about 5 min. I turned it on and it was bright for about 2 seconds then it went dim.like less then 1 mw.there’s no way I burnt it out it wasn’t even warm. I emailed sanwu but is there anything else I can do in terms of troubleshooting?

You can try bypassing the tail cap switch ( safely ) as sometimes a tail switch can make a weak contact and cause low output issues.
Just use a piece of wire and see if it's the problem or not.

Hey it happens to us all, just remember to wear your laser safety glasses when working around anything reflective or up close. :)
