Can somebody explain these terms to me and or show me how this driver would be wired in a case positive laser ?

Where is says LD+ you connect the laser diode anode, and LD- is connected to the laser diode cathode. Power VE + is where you connect the power supply's postive side and power VE- the negative. The current pot is used to set the current the diode will run at and should be done with a dummy load before you connect the laser diode.

You are welcome, Accutronitis. It sometimes takes me a day to respond to questions, so don't feel I'm snubbing you if you have more questions.

Do you mean questions about this driver or questions in general ? Because I always have questions ! lol

I always try to be as helpful to members as I can, but I can't be the encyclopedia for the forum. I'll do the best I can when I am online. :)

First, I'm assuming that you have a dead laser pointer and are trying to replace the laser diode and the driver. All the Thor M2 lasers I found were around 455nm, but the power output is different depending on which one you buy. Wiring a blue diode with the case positive is unusual, but no reason you can't do it that way. Personally I'd leave the case pin floating and not connected to anything at all. Is the driver in the photo the same one used in the original laser? If not, it might be too large to fit in the confined space you have in the host. If you are using a diode from a ca$io projector, it can be set to output between 1.5 and over 2 watts depending on which diode you are planning on using. Either way, with the pins facing you and the case pin (2) in the down position the pin on the right is the anode (positive) pin and the one on the left is the cathode (negative) pin. Then the connections will be the way I stated in my earlier post.

No I didn't have a dead diode And it was wired case positive when I got it AND the diode case pin (2) and the anode (positive) pin on the right both went to the driver together, What do you make of that ?


But I am replacing the driver and yes the driver in the photo is the same driver that's in my laser

The driver I have coming is a X-drive 1100mA Fixed and does not have a continuous ground so I was planning on following this other members advice that I found during a search, And it go's as follows.....

Most hosts are case negative. If your driver is continuous ground then what you will need to do is bridge the case pin and the negative pin of the diode together. This will supply your driver with the negative from the case of the host. If the driver is not continuous ground then you simply solder a jumper wire from case pin of diode to the drivers negative input side. No worries you will be fine. It seems scary but once all your components are in front of you it will be just fine.

Unless anyone has any objections ?
