Anyone with one 445nm 200mw diode?

Hello everybody,

Im searching for a not so exspensive (cheap) diode.
A blue 445nm 200mw, used or unused, tell me if you have one!

Sirencely, Jurre

Output will be determined by the current which you choose. Also, several members who call this place home sell them. Check out the Pro Shop. If you need a host to set that sucker in to, check out one of my threads, here or in the Pro Shop. Good luck.

Hi, thank you for your reply!
So the output in mw/w depens on my driver and powersource?

I have the following aixiz mini houssing : click650nm 5mw laser module 8X13mm:Amazon:Electronics

So i will get 1W with this driver?
Anyway i gonna take a look at the pro parts

And this driver: Clack

You have to check and set your driver to your desired current.

How do i set? resistors?

How you set the current depends on the driver you are using. Some require soldering resistors. Some have a potentiometer to turn. Others have other methods.

I would suggest that you spend some time with the very useful search function on this forum. That's how I and most of the others here learned.

I also suggest that you read the safety stickies as well as the stickies designed for newbs. There are quite a few really good guides that have excellent info for someone starting out.

That's not a mini housing, that's a red laser. The diode might be removable and you might be able to put in a 445, but that's a bad/undesirable way to do things. If you're spending ~$45 on a 445nm blue diode, you should spend the extra $3 to get a proper aixiz module.

Nope. That's an ok driver for your first build, but expect more like ~600 to 750mW of actual output from your diode.

Thanks for all the replys!
I gonna spend some time watching "newbie" stickies

As so far: the driver should be 1w but, it will never get so high.
But if the current is set to +- 250mw and your diode can only handle 200mw your diode dies soon. My driver has no screws/buttons to change the current so i need to use risistors.

As rhd says its a red laser: well it is, but i pressed out the diode so i can put in my new one
Isn't it the same as using another aixiz housing?

About safety: i started with reading alot of this: i think safety is the most important thing. I already bought a set of laser goggles.

I don't know if it "should" be 1W... but they advertise it that way. In reality, it just doesn't supply enough current to a 445 to achieve 1W[/quote]

There is no such thing as setting "current" to 250mW. Current is measured in mA, not in mW. They are entirely different measures that you are confusing. You would definitely be well off to brush up on some electronics terminology before you undertake a build. I understand the confusion, because often (not always) our 445 diodes tend to put out the same output power in mW as the numerical amount of current in mA that you put in. This is just a fluke that occurs with 445s though - because current in mA is not the same thing as power in mW.

A red 650 laser diode might take 600mA of CURRENT in order to produce 350mW of POWER.

Another comment - there is no such thing as a 445nm diode that can only handle 200mW output (unless it's a broken diode). I believe this has already been addressed in this thread. 445nm diodes are ALL essentially the same. There is no "200mW" 445nm diode, there is no "1,500mW" 445nm diode - they've all the same diode. Ray J Neal explained this to you at the beginning of this thread.

No... this is where you really should have been doing research before posting. The "Aixiz modules" we use commonly around here look like this:

Hi, i think i said current because my bad english, i didn't know which word to use.
But i know the difference between ampere and watt and voltage

So all 445nm supports ~1W?
And all 405nm supports 100mw-120mw?
Etc.

I wass also watching for a 405nm diode as firts build. But i sawhere
That they can create only upto 120mw of power?

There is only one type of 445nm diode that we commonly use. It can output 1W (or higher). You can also run it at lower currents, and get lower outputs (if you want to).

There are many 405nm diodes. Some can output 100mw-120mw. Some can output a lot more. Some can output a lot less.

Oke i understand ; some lasers are in different types of power.
but there is just one type of 445nm bieing used.
