    beginner try to make is own laser !

    If you want to make a 1W green laser you're going to have to do a lot of research and put in quite a bit of money. If you want to burn stuff go with a blue laser thats 1W+ you'll be more satisfied for the amount you spend. Tbh green lasers at 5mW-20mW hurt my eyes. So if youre going for a 1W...

    Approximating laser power without LPM - A scientific way

    well i mean i guess i could be selling Chinese lasers, or i could have bought one realized i got a Chinese laser, and want to return it or have them ship me the proper power module to replace. What is sufficient proof? I figured fighting fire with fire (false advertising vs. false proof) would...

    Need a picture of a LPM measurement for a green laser

    Not to worry I completely understand where you're coming from! Hopefully I can get an LPM when I can afford it so is can get real and accurate readings ^^

    Need a picture of a LPM measurement for a green laser

    Yeah, I accepted that and decided to just try testing it, I tested it about 5 times and averaged it to the low 40s. +/- 20-30mW is still nowhere near the 200mW that was advertised :p who knows I could have a 5mW laser pointer LOL my eyes can't tel the difference while wearing my green blue laser...

    Need a picture of a LPM measurement for a green laser

    Well I'm sure people have a 4000mAh 4.7v battery for other lasers, it seems pretty common. I'll see if I can find someone around Sacramento- San Francisco area with an LPM. Otherwise I'll be looking for a vet to test out my laser. If it turns out that they won't refund me after too long I'll...

    Need a picture of a LPM measurement for a green laser

    If it was that simple I would, but being from Hawaii there aren't many options. Shipping anything from here is hell, not to mention with a rechargeable lithium ion battery -.-

    Need a picture of a LPM measurement for a green laser

    I have done tests thought up by others which have a relatively fair amount of accuracy being 15-20% off. Both tests brought me around the low 40s which I was expecting. I was very skeptical about getting a 200mW laser for around $55. All I want is a refund, but The seller (from Amazon market...

    Need a picture of a LPM measurement for a green laser

    Yes that's all I need, and it is an odd request. But 40-45mW is good 50 is also fine if that's what is being read. But it can't have the actual laser pointer in the picture, but the beam is fine.

    Need a picture of a LPM measurement for a green laser

    Thanks for the reply Trevor! I went ahead and check out that thread prior to starting a thread, but unfortunately I live in Hawaii and there is no reasonable way for me to meet with someone or ship anything since it costs quite a bit extra to send things with a battery and a lot of extra time...

    Need a picture of a LPM measurement for a green laser

    I was looking for someone who could help me get a picture of a measurement in the low 40mW range? I need to return a laser and in order to do so I need to show them a real measurement from an LPM. I used some methods on the forums that use IR thermometers or measuring the temperature change in...

    Approximating laser power without LPM - A scientific way

    First time on the forums and I am learning a lot! But I have a request for you or any other member. So I have also tried this method with a "200mW" green laser I bought. I was expecting somewhere around at least 100mW seeing as I purchased it for about $55 (I know cheap for a green laser of...
