Hi, i have a 1W Aixiz driver: click.
I dont know why but i cannot find any information about it, i dont know how to set the current etc.

Wel, i want to use it with the 405nm diode from xbox hd-dvd.
Extracted from sled :pHR-803T
Can somebody tell me if i wont kill my diode, and how to configurate my driver?

hello there,

I have a few of them and they are fixed current drivers, in order to adjust the current you will have to limit the input current or change one of the resistors on the driver.

They are best used on 1W 445 diodes cause they can handle 1W+

Hi, thanks for the reply. In the description was the following: Also suitable for 405nm 200mw diodes.
What does fixed current mean? Does it mean it will always output 1W or something?

Thanks for your help,
Jurre

I dont see how its suitable for 200mW diodes without modification.

you are correct, fixed current means it will always want to output 1W.

O-like sells the same driver: 1W 445nm laser diode driver / 200mW 405nm laser diode driver [OL-445-D] - $14.99 : Welcome to O-Like.com, Your source for laser products but they don't have any documentation either.

It states that output voltage: 4.8V with output current: 1.1A. My guess, and it's just a guess, is that when hooking it up to a 405nm diode (6X or 12X), the output voltage goes up to ~6V (thats what 405nm LDs need) and the output current drops. But someone would have to hook it up to a dummy load and do some tests.

I wouldn't use it with a PHR. If it says it can run a 405nm at 200mW, and it's a fixed regulator, then it will output too much current for a little PHR. It will likely kill it fast.

Hi, think its so strange why isn't there any documentation??
B.t.w i switched to a 6x bluray diode 405nm thing this one can handle 200mw?

Well, if 4,8V mean 1.1A, i dont think 6V means the current to drop enough for a good diode life.
Difference between 1W and 200mw is big..

yeah, i don't see how that driver is not going to kill your 405nm, for what i know, 405 and 445 have the same internal voltage drop and resistance so it will apply the 1000mW to it and destroy it quite easily i should think.

do you have a test load? if so, would you please tell the results?

At 4.8V, any 405nm diode will have a very low current. Because the maximum voltage consumable will be 4.8V, I would guess that it would only be able to eat up roughly 250mA of that 1.1A of current.

However, the 445nm has a lower Vf, so at 4.8V, it can eat up much more of that current, around 800mA (pretty sure it can't eat more than that... I tested a 445nm diode at around 1.3A and the Vf was around 6V).

But its a cheap driver, so maybe it can't even output 1W.
So , lets say the driver can output only 800mw, then the current for the 405nm will be even lower.
How many V and A does it needs to output ~200mw power?

Well here are the ebay specs:

That depends on a couple of factors:

1) Some LD's are more efficient than others. For instance, one 6X might output 200mW at 190mA and another might only output 180mW at 190mA.
2) Optics. Depending on what lens you use. For instance, Jayrob's G-1 405nm lens will give you ~31% increase in power over an AixiZ acrylic lens.

The last 6X I had was putting out ~190mW with the driver set to 190mA. This was with an AixiZ glass lens. I put the G-1 405nm lens on and it jumped to 223mW.

The driver you are talking about needs testing done to determine it's true capabilities. There is just too much unknown about it.

When you get a chance, take some time and explore the links in my sig.

That AixiZ driver afaik is best used with the 6X 405 and the 445 diodes only(not meant for a PHR). I have one running a 445 nicely and the output is ~850mWs. , This is on a 18650 battery iirc. The build was done by DTR and he can be very helpful as he has experience wth this AixiZ driver.


IMO the only way a 445 diode would putout 1W with this driver would be if you got lucky and had a highly efficient one. And.. I see no pot on this driver for to to 'set' .
Did you try asking AixiZ for more info? The username on LPF is 'cmaricle'.
Chuck is not here every day so you mnay want to also send your questions to him in care of www.AixiZ.com .

good luck--hope this has been helpful. hak

i agree with kevlar and hak. even is it was adjustable in the product description it says its range is 300ma-1000ma.... a phr can't really handle more that 120ma.
