Hi guys, i am new to laser world, and after research the forum i bought an 200mw RPL from optotronics, when i unpacked it i was surprise! They sent me an 225mw! But there´s one question: When the laser is cool down and i turn it on, it light an match in less then one second, and after its on for more then 40 seconds it starts to lose power and it doesnt even light an matche, so i need to let it cool down for about 3 - 5 minutes, to have it maximum power again, is this right? is my device with problem? Thank you.
