Why did you buy them? Do you have any intended purpose other than a 2W laser?
They are surplus diodes, probably not good enough for DPSS pumping. They are also multimode, so you won't be getting a good beam from them at all. They are IR, and will be very dim to completely invisible.
Those diodes are also from Heruur, or Chris. Some people have had issues, some have had no problems at all (I'm part of the latter.)
They might be fun to play around with if you know what you are playing with and how to protect yourself but not much more.
Honestly I couldn't say... if no one here has bought them then its up to you to do a review
I guess I will do a review on them once they come.
And no I didn't have a specific purpose for them, was thinking about attempting a dpss someday but not anytime soon. Mainly wanted to build an IR laser just to see what they are like and I thought this was an affordable way to do it. If they are of good quality maybe they can be pushed past 2W, we will see when I get a chance to test them.
I know about the low visibility and the dangers that come with this and I do have safety glasses for this wavelength.
They generate less than a third of the heat of a 445 run at 1.8A. If copper isn't necessary for 445 (and it isn't) then it isn't for this diode, either.
