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...

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...

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...

Hi all, Here are some beamshots of my new 9mm 445nm Nichia diode. < 3W. The lens used is the 405 G-2 lens. Could you guys please take a quick look at let me know what you think? Thanks :) :wave:

Hi guys, I'm looking for someone with experience with IR diodes to have a look at the pictures that I've uploaded to my other thread below: http://laserpointerforums.com/f67/opinion-lm2596-based-driver-77901.html#post1120816 I figure that this is a better forum to post the question as this...

Hi all, I can't ignore the fact that this driver costs just £2.99 and is both constant current and constant voltage adjustable. It seems to be of quite good quality. Question is, what's the catch here?? With my limited knowledge I'm not sure what else to look out for and could use any opinion...

Hi guys, I'm having trouble locating and guides for pressing a 9mm diode into a TO-5 housing. Could anyone please suggest some tools, techniques? That would be much appreciated. Thank you very much.

Hi guys, I'm thinking of purchasing this: One extra high burning power (1000-1500mW) infrared TO-5 9mm laser diode + Gift | eBay However the listing does not list the diode's make/model. It does not list the recommended driving current and voltage. Could someone please help me to identify...

Hey all, I've got a PHR mounted in a case, etc. etc. driven at 107mA and I only keep it on for 1 min at a time at max but yesterday when I turned it on I noticed there was about a second lag between the time the switch was turned on and the laser beam getting to it's brightest. Today it has...

Wow, is this legitimate? Seems like a great deal to me. http://www.o-like.com/b2b_cpinfo.asp?id=1053 http://www.o-like.com/b2b_cpinfo.asp?id=980

Hi all, Just curious to know why blu-ray lasers are so dim compared to red ones? I could point a red laser at half a mile away and see the dot but I can't see a blu-ray's dot clearly on my neighbour's wall. Is it because our eyes can't pick up near ultraviolet as well as visible light? Also...

Hi guys, I'm just curious why the PHR-803T puts out so much power? First of all it's from a HD-DVD drive rather than a blu-ray drive. Secondly, the drive that it comes from isn't a writer. It only reads discs. So how come it's about 1/3 the power of an 8 x Blu-Ray writer? Thanks guys.

Found this wonderful laser encyclopaedia and wanted to share it with everyone here: Encyclopedia of Laser Physics and Technology - an Open Access Resource of In-Depth Information, Free Articles, Nonlinear and Fiber Optics

Hi all, sorry for this silly question, but I feel safer asking and doing it right :) I've got this glass lense: AR coated glass lens for laser focusing modules [LENS2] - $5.99 : Modwerx Shop Now the question is, how do I use it? Is it a direct replacement for the stock acrylic lens in the...

did anyone participate in this crazy idea last time?? Paint the Moon given the fact that our moon wasn't obliterated I'm guessing noone from LPF joined the effort?? lol!

Hey guys, I've got a PHR-803T in an AixiZ module with acrylic lense (opening cut out) and I'm driving it with 110mA of current. I can't seem to 'burn through a black CD case' like those ppl can and posted their vids on Youtube. I wonder whether it's because I'm not driving it high enough? I...

Hi all, Just trying to figure out how to install the LASORB. Should I just wire it in parallel with my laser diode? More importantly, does the inclusion of LASORB change anything in the circuit? Would I have to dial up the mA on my PSU? Thanks.

Hi all, Quick question for the electronics experts. I have DDL's PSU which comes with a voltage and amperage adjustment pot. I have a 1 ohm resistor connected in series at the output. I now need to solder on a dummy load so that I can adjust the voltage and amperage before hooking up the...

Hey guys, What's that lense he put there? Is it just a magnifying glass? How come the light beam still comes out straight? http://www.youtube.com/watch?v=l1vlNpLq-Dg Thx.
