658nm 1000mW Laser diodes?

[allthatwhichis]

I would be happy with 5000 hours life, so long as ongoing supply is available.

Shiiittt... we'd all be happy with 2000 hours as long as we each have a handful.

Yeah, but I can't see an amp going through "that" driver. If it's too good to be true, it usually is... We'll see though. I'll eat my hat if they make close to 1W even with a flashlight beam.

Maybe. 1000mA is not a lot of current.

How close to 1W will you eat your hat? I want photos!!!!

We'll see,,, hat and camera waiting....

These may be different diodes, but if they are, I can't tell which ones. Maybe we're lucky and the LPC826 diodes turn out to be as tough as the Nichia 445's, so you could squeeze a Watt out of them in a single diode.

The LPC826 dies at 650mA. So that's probably not the one used.

It would have to be a C-mount diode yes? Look at the photo again, it doesn't appear possible...

It must be a decimal place diode!

Couldn't it be a bigger model can diode ?
I mean we all use the 5,6mm but i thought there was also a 9mm can model ?
Maybe it's a open can in a 9 or something mm can ?

100um emittor and 670nm
670 is not really visible very well. It's worse than 660, which is worse than 642
I mean a 642nm is often quoted to be twice as visible as 660nm, i mean 670nm ?
Yeah nice to have a Watt, but visible would be cool too.

But higher powers will be there hopefully.

Kind regards,

Yes I've got 2 comming. I'm just curious as hell to check these claims. Actually 1200mA is the operating current, the 400mA is recomended for getting the 20000 h of operating time. Well I'll see shortly.

cheers!

It's a pointer core, so take the 1200mA with some grains of salt. The thing may be able to take it for several seconds, but not as a continuous run.

Even that would be amazing. I've googled for about an hour now and the highest cw power on 658nm diode (5.6 or 9mm) I could find in a pointer was @ 500-550mW from Laserglow and costs 1498$.

So if it doesn’t reasonably meet up to the claims, it will just be another PP issue.
