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:

The 3 diodes appear to...
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 :)
But but but it says it's 50W.... What's their real output then?? Hehehe. Check this out:

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...
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...
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...
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...
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...
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...
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.
Hi guys,
So I complained to the seller who sold me the 808nm diode in my other thread:

The seller has sent me a replacement. This time I was very meticulous in ensuring it's properly handled, pressed into the copper module...
