1W 638nm FAC Diode

[Phillip]

Hello!
Does someone have the 1W 638nm FAC Line Diodes for sell ?
Thanks and BR,
Phillip

Yes, I believe I have a few left

I just built one into a custom pointer...

That's the worse beam spec 1,2W diode.

All the multi-mode red diodes are pretty terrible.

Try ebay phillip. I see them a lot but have not looked lately.

 

[dubious speculation]

lasertree sells them for 70 usd on both Aliexpress and ebay.

They also sell a 2.4w 638nm with FAC with the same claimed divergence.

The 2.4W is a double beam diode, I believe the original manufacturer is Ushio

The 1,2W Diode is much worse compared to the 1W diode.

Seems like nobody is making/selling the 1W diode anymore.

According to the photos and the datasheet supplied it's not. I've only seen the tri-beam monstrosity before. I'm more inclined to be skeptical and assume that you're right. But if the datasheet is actually accurate then that's way more interesting.

Do you have a data sheet or links to support this? Interesting.

The 1.2w listing and datasheet match the datasheet and diode used by styropyro in his video here

Crazy Keychain Laser Pointer Upgrades. 5mW to 3000mW+

He had great results and the fast axis correction works very well. What's the rated divergence of the 1W compared to the 1.2W?

My gut tells me it's a Ushio HL63520HD that's had a FAC added to it, hence the price increase over the regular diode. Both the Ushio and the LaserTree data sheets show the same double diode in the spec sheet for the pin out.

For multi beam lasers I quite like the Mitsubishi line up.

Oh you're right! Just looked at the listing more closely and indeed Lasertree show a dual diode diagram on the pin out despite the misleading image of a single square beam output.
