Ok, now I got some time to check those with a multimeter. You are right: They are case positive! Now I got 2 635nm LEDs. Thank you very much. At least there are still 4 untouched laser diodes...

For the flat plastic diode try center pin positive, one of the outer pins negative. Worked for me once, but I´m not too sure of this, so don´t blame me if its wrong ;-)

ok, only the diode on the left is a 5.6mm (standard format) laser diode. Imagine a Triangle with the top on the right side and the longest side on the left ( middle of laser diode). Now the upper pin is positive, the right pin is case and negative and the bottom pin is the (mostly unused) photo...

Seller claims it´s TL, but it obviously is not the "case" - thanx alot, I don´t have much time left today but I will try tomorrow and post the results.

anyone? an idea what i´m doing wrong? Laser diode is DL 6353TL ; datasheet: http://www.laser66.com/html/DL-6353TL.pdf

what about pinout? datasheet said like dvd-diodes with case negative, but I powered 2 diodes, first with 30mA then with 50mA according to this, but NOTHING happened. No LED, no Laser, not even a faint red led.

thank you for the quick reply! I thought of driving it @ 45mA or so. The driver seems to be PD feedback regulated, so I can´t check this with a dummy load.

some 635nm diodes arrived today (7mW rated). Can I use the driver from 5mW laser modules (AixiZ/Sure) to power them at reasonable current?

Ok, guys...sorry for digging this old thread up...should have checked the date first, but I was in a hurry. ---silently beaming away---

Dragon Lasers for being f*cking expensive

50mW of green will be oticeably brighter than an LOC. 20-30mW max should be equal brightness. typically less.

I was able to move particles (from iPod leather case) for a quite long time. Video *in HD* on Youtube: YouTube - Optical Trapping!!! Laser: LOC @ 420mA with AixiZ Glass lens

Hi! I´m new in the forum, but not all new in killing laser diodes. This thread remembers me of some strange sled I´ve extracted once. It was called "LPC-817" and I found it inside an LG GSA-H20L DVD burner (broken) I bought for diode extract on ebay. It had the LOC diode, which is driven by a...

rkcstr river should be ok for an IR diode. Set it to 250mA; @ that current the diode will need around 2.2V. So 5V input would be enough.

Although this thread is pretty much dead: CD burner diodes can be driven safely at 250 milliamps (at least none of my 52X diodes died at that current). Their limit is at something around 300mA, I think, but some diodes die at 380mA or so.
