    Ohh yah that is indeed 50GW :) That's still nothing compared to the one fired from the Death Star :)

    Lasers on Aliexpress.com

    I'm not the one who's kidding. The people who list them on Ali Express are. Of course these can't be 50W.

    What diodes and power are these?? BMW Laserlight

    Hello, Just curious to know the diode specs (at least diameter, wavelength and wattage) for the Laserlight head lights on new BMW vehicles. For those who haven't seen them, here's a good and short piece: How It Works - The BMW i8’s Laser Headlights - Popular Mechanics The 3 diodes appear to...

    Lasers on Aliexpress.com

    Hi guys, I've received this 50,000mW laser from AliExpress today. I was going to write a review about it, but then I've found the item listed and sold accurately here: 100mW 532nm New Flashlight Style Green Laser Pointer Pen with 18650 Battery at Laserpointerpro.com So it turns out it's only...

    Hahahaha it's not impossible. The IMR type 18650 Li-Ion cells can have a discharge rate of 10C thus you could draw 15Amps. 15 x 4v = 60 Watts. Theoretically possible :)

    Lasers on Aliexpress.com

    hmm hmm at least Aliexpress has a good buyer protection system. Anyway, I've always wanted a green 523nm laser so I've bought one. 50,000mW for just $8 surely can't go wrong :P On a serious note, the laser that I'm referring to is listed as 50,000mW everywhere, but it's a very common 1W green...

    Lasers on Aliexpress.com

    Hi guys, I've just seen some crazy laser prices on this website. I'm sure most are complete rubbish as they even have 50W lasers on sale for under $10.00 The whole thing is just too good to be true. Anyway, what's the deal with this site and what can one expect when order one of these...

    replacement 808nm diode still can't burn. seems severely underpowered again :(

    not anymore as it's all boxed up nicely in the enclosure. I'm not sure if a picture will help. I've made several other builds successfully.

    replacement 808nm diode still can't burn. seems severely underpowered again :(

    ok since I already spent money on everything else and built the enclosure, etc. It makes sense to order a similar diode from a different seller just to hook it up and see what happens. I've found someone in the USA selling one that is rated at 1000mW so it should be a more reliable option to...

    replacement 808nm diode still can't burn. seems severely underpowered again :(

    Ok I can help. Here's the link to the diode: One extra high burning power (1000-1500mW) infrared TO-5 9mm laser diode + Gift | eBay It's listed as between 1000mW - 1500mW I've tried using both Power Supplies. Both links where provided. The latter is current regulated. Yes I did short the...

    replacement 808nm diode still can't burn. seems severely underpowered again :(

    Ok just as an update, I've used the second driver that I've listed above. I've confirmed the drive is driving the LD at 1.2A and yet the results are the same :( Now 2 supposedly good diodes are giving me the same results. I'm wondering if this seller is just selling weak diodes as high powered...

    replacement 808nm diode still can't burn. seems severely underpowered again :(

    Hi, OK here's the 'bench' power supply that I'm using: LM2596 DC 7V-35V to DC 1.25V-30V StepDown Adjustable Power Supply Module LED td | eBay I also have these: High Current LM358 Laser Diode Driver (445nm Diodes, Infrared and Red Diodes) | eBay Dummy load = 3 pairs of 1N4001 diodes in...

    replacement 808nm diode still can't burn. seems severely underpowered again :(

    Yes I've got a constant current driver, set to drive it at 1.15A. Current output has been verified many times with various diodes. Ampmeter always reads 1.15A through the diodes. Thanks.

    replacement 808nm diode still can't burn. seems severely underpowered again :(

    Hi guys, So I complained to the seller who sold me the 808nm diode in my other thread: http://laserpointerforums.com/f40/my-ir-diode-dead-77935.html The seller has sent me a replacement. This time I was very meticulous in ensuring it's properly handled, pressed into the copper module...

    is my 445nm diode OK?? beamshots attached

    Yes those are precisely what I was looking for. I didn't realise they were tailcaps too otherwise I would have found them ages ago. Thanks.!!!

    is my 445nm diode OK?? beamshots attached

    Apex: I'm using all the lens caps that I have at home. Do you know where I can buy some more for these AixiZ modules? Thanks.

    Thank you mate.

    is my 445nm diode OK?? beamshots attached

    This isn't the M140. The M140 is a 5.6mm Casio diode right? This is a 9mm Nichia diode which is around 500mW more powerful than the M140.
