^^ It looks like the seller isn't even sure what diode that is. They are taking a guess from the "closest specsheet they can find", the ML101U29 (LPC diode). So that's all we've got to go off.

It's tough to tell how much power you are going to get from feeding any diode any given amount of current. Each diode varies a bit, so it's not an exact science.

If it is an LPC-826 like the seller suspects, you can give it 450-500mA no problem and it should be about 250-300mW. The only way to tell for sure is buying one and trying it out.

Welcome to the laser hobby. :beer:

Thanks. I don't really feel like buying a diode on "trial and error", You don't happen to know where they sell red 250mW laser diodes where the seller knows what mA you should use? :p

Thanks for the tip man. Quick question though, Why does that first one (lpc-826) not have any metal casing around the tip like every other diode have?

The metal casing is called the can not all diodes have it. You can also buy a decaning tool to decan diodes.

also these diodes are called LOC diodes ( Long Open Can Diodes)

What does the can do? Is it better to have a can or not?

Some think decaned diodes have more powerful but there better because there is no fragile glass at the front of the diode.

So I should be able to use it like any other diode (Put it in a axiz module for example), as long as I am more careful?

one thing no touch the front parttttt¡¡¡¡¡¡¡¡¡ you can damage the diode

Yes as long as you get the pinout correct quickly solder the diode and use esd protection.
