Well I tested it again today with a bench supply. The other diodes which were not lasing did lase at Vf > 4.8 and at 40mA - 90mA is when you get maximum lasing. Wonder what this laser is. And also the pin config does not appear to be standard (will confirm and let you know). May be these have a...

But that is like a 1W phaser. I believe 20mW beam is also quite noticeable. The seller I purchased from has however denied any replacement saying no warranty with these lasers.

I am sure they are faulty. I did allow my current to exceed beyond a limit of 35mA. Also my driving voltage was 4.5 to 5V. 3 of them just dint light up. I have handled many laser diodes till now. I have machined them and extracted them as well. They worked as I bought them. I made new drivers...

No point in posting the pics now I guess. The diodes that were shipped to me turned out to be faulty. Changing the input current also did not change their intensity by much. 3 out 5 diodes shipped don't light up.

Well I checked all the 5 diodes. 3 are not giving any output and the other 2 are giving a very low intensity output which is not even like a 3mm LED..very crappy..

Ok. Look at this diode : http://cgi.ebay.com/ws/eBayISAPI.dll?VISuperSize&item=360025407620 http://www.ebay.com/itm/20mw-blu-ray-laser-diode-405nm-Kip-Kay-project-suitable-/360025407620?pt=LH_DefaultDomain_0&hash=item53d32fc084 Look at this baby: 405nm 20mW Laser Diode 5.6mm TO 18 Package...

I ordered loose diodes and they did ship them so..I requested for a data sheet.The ebay listing for kipkay 20mw laser from aixiz also does not show any pin labeling and their laser drivers are also overrated.

I take enough care to touch a metal part before handling it. Non of the things I handled now died so. Just tested other diode and it is also not working. I still could not get my hands on a bench supply. I have handled many laser diodes (red and green) they all were fine as far as the ESD is...

Well I tested it yesterday with 4.5 Vf a I at 25-30mA dint get any output. It was not from a constant current driver so I guess it was not able to maintain the V-I required. I will test it with a bench supply today.

I have seen the sony diode sld3131vf with the same config. Here is link from thorlabs which shows blue ray 405 nm in B ang G configs.http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=7 I cam across a similar page for different configs in sam's laser FAQ but not able to find it now. It...

I need the pin connection for this 3 pin diode : http://www.aliexpress.com/product-gs/359487444-Free-shipping-10pcs-lot-Laser-Diode-for-PS3-KES-410ACA-3-pin-video-game-accessories-wholesalers.html

I also think the same but I do not know about the pin diagram of this blu-ray diode. Could you please post your pin connection (a picture showing the back of the diode with the legs labeled would be great). I will test it with a bench supply. I did read the article earlier but it is for a 5 pin...

Hello could you please let me know the terminals on the laser diode.I bought one such laser and I am not able to get it running. It would be great if you can post a picture of the back of the diode and the pins labeled. The diode that I am using is this: Wholesale Free shipping Laser Diode for...

Well I am not thinking of getting it into the PS3 but just make it work as a laser pointer. So how shall I light it up? In reverse polarity will it not fry the diode away. Even 15mA higher than the rated current in the right polarity can damage the diode. Genrally high power LEDs or normal...

Hello, I recently purchased couple of PS3 Blue ray KES-410ACA laser diodes Wholesale Free shipping Laser Diode for PS3 KES 410ACA (3 pin) video game accessories to make a laser pointer but I do not know the pin out of these diodes and their voltage-current ratings. The closest match I think...
