I have just purchased a laser 303 which is DPSS. I keeps flickering and going dim. I have heard on this forum that you should warm it up for 5-15 mins and I am not fully sure what that means. I'm not sure if it means to literally heat up the laser or to keep the Beam going for a while. I am new...
Hello,
I recently purchased a laser 303 and it was working fine where it can burn and everything. But recently immediately after I turn it on, it quickly dims every time I turn it on. The battery is fully charged. Please help because I now cannot burn thing and I have no idea what to do.
