SUPER FREAK "445nm diode"

[lazeerer]

I hate having conversation with members before bed about efficient diodes because it gets you excited. So excited that it makes you crack some M140 up and start testing. Damn You. Mind you its 1am now.:shhh:


This is the best 445nm diode i haver ever owned Tested whtever you want to call it.

I dint say the max but its well over 2.5W.

Ugh!

Must you torture me!

Nice find.

 

[Tech_Junkie]

You just gave me a chubby. :bowdown:

 

[jayrob]

Wow nice diode!

You said 2.5 Watts with 405-G-1...

What current was that? 1.8 Amps?

YES>!:na:

hehe.

You miss heard me. I said its well over 2.5W with a G1 lens.

I tested it up to 1.76A.

You will have to wait for the build to see what the max Currant and Power is in a few days.:na:

I'm guessing maybe 2.9 watts.....or 3.1 if you got usper lucky?My gut says 2.8-2.9ish

Keep Dreaming. If I got that i would be build the laser right now. 2:30am.:crackup:

Personally, if I had a diode like that, I'd just set so that it was giving me 2 Watts and hope for good longevity...

Nah. I get 2W diode all the time.

All my 2W laser are still going strong. Have never seen one even Degrade at all. Some of my 2W laser are over 1 year old and those 2 i use the most and run them for long Duty cycles.

So If all my other 2W lasers are set to 1.76A and putting out 2W+ and this one at the same currant is putting out >2.5W it will still have the same Long life as my other ones. Possible more because its so efficient.

I have yet to hear to this day a 2W laser dieing from natural causes

 

[eytyxhs]

Damn!!

I never had >1.7W diode at 1.8A.
You were lucky!

I think it's time for this: http://www.casio.com/products/Projectors/Pro_Models/XJ-H1700

Maybe they can run >2.5W

I meant to add 2 Watts through an O-like lens because of the better looking dot...

Although that would be nice, I would never run anything about 1.65W-1.7W without a G1 lens.

Thats just asking for it.

There is so much heat restriction going back into the diode at that power also not to mention reflection that i just dont trust it.!

You would be crazy to run a 445nm laser off an Aixiz/O-Like Lens at about 1.7W or higher. Just my own train of though.:undecided:

 

[Tech_Junkie]

So do you think we are running at the limits of these lenses?

Hmmm... Good point.

Your right in that there would be quite a bit of light trapped inside at that level of output. Best to use the 405-G-1 to let as much as possible out...

IMO Yes we Are.

Using a 3 element Glass lenses restricts so much power that it has No where to go but generate more heat.

Not only does a G1 lens give more power you will find that that same build that you had a 3 element glass lens on before switching to a G1/G2 lens was running hotter with the 3 element lens then with a G1/G2 lens.

A Focus adapter also helps.


Now there is also the amount of light it restricts. Because it clips the edges,has to travel through 3 lens etc that cause back reflection and More Heat.

Although you would probably be fine ruining it at that power with a 3 element lens for a little, over time IT can degrade the diode, Lower your duty cycle etc.

I think the way to go is if we want a better dot, use correction optics. The Loss will still be less then using a 3 element Glass lens. Problem is its not s easy as it sounds. Trying to work on something now.

The 3 element glass lens is just cheaper and easy to find.

You jerk - now you're keeping me up too ;p

I'm working hard, but I'm a lot slower at binning diodes with my setup. I'm about 16 diodes into the H-series. So far, 2.55 W with a G lens is the best from this array.

I'm tryin here! And I don't think my girlfriend appreciates being kept up for... well this.
