Re: Worlds most powerful handheld 4.4W 445nm

Arrr heck. cant give rep again till...blahh blahh.

Arg, thats a beaut - 4.4w of delight
(could it be 4.45W of 445nm?)
More picks / more vids / more more more

Re: Worlds most powerful handheld 4.4W 445nm

Don't forget to add some vids :gj:

Preferably some wall burning ones

I will, later today. Last time I tried to video a laser my video camera display went all red, hopefully I can figure something out to video this.

Wow! That is fantastic!!!:beer:

So what did your neighbors say after they saw it? :eg:

Thanks! It was something along the line of "Holy shit!"

Are you able to adjust the focus / are the flat part of the dots or "wings" aligned on the same plane?

The laser is not focusable, it's fixed focus. I used a waveplate so the beams are aligned in the same way, it makes a | instead of a +.

Well done man... + 2

Shes a monster.

Thanks!

Yep, I get this general feeling with all 445. Have accidentally put a few burns in the walls, and outside the beam is insanely visible in the sky, almost like a huge illuminated arrow going "Guy with an illegal laser down here!"

Kinda need ultra low power modes, maybe run just 1 diode just above threshold?

Yeah, even running each diode at 220mA I was getting 250mW out of this laser.

Awesome build man! I really like it!
Smeerworst must see it

Thanks!

meh. The alignment sucks balls.



j/k it's awesome +1 as I promised you.

Thanks! I didn't realise the beam was coming out of the laser at a funny angle until I had everything done. It's not a huge deal, and I'm definitely not messing with the alignment again after it took me so long

wow Arg, that's amazing :drool:

I will + rep you when I can

Glad it turned out well after all that work you put in

Thanks! I'm glad it all worked out in the end too, I had my doubt about aligning optics in such a small area.

I will + you if you make it + beam !

Just kidding ..

Yuck + beam I like having the same beam specs as a single diode laser

It could have been 4.5W. I am running the diodes at 2A each. If I was to run them higher I could have gotten more power. I did not want to run the diodes that high because then they degrade faster. I'm okay with doing it in a single M140 build, because the diode only costs 50$ to replace, but the diodes for the laser are almost 200$ to replace and would not be a simple task to replace because the alignment would not be the same.

Nice man... a slot to open up and view combining cube would be over the top, but that's messing with perfection.

It would be neat, but the optics tray looks messy I didn't design it with ascetics in mind, just functionality and longevity.

All I have to say is WOW :beer:

I really want to see some videos of this MONSTER !

Thanks everyone! I'm working on the information/multimedia thread as I type this. It will be up tonight for sure.

Where did you find an appropriate wave plate? Will any optic work for 445?

Edmund has 1/2 waveplates, but their prices were way to much. I ended up getting this one for 40 pounds. 1 2 Waveplate Blue

Re: Build thread: Worlds most powerful handheld 4.4W 445nm

Again, Great Job. Absolutely Phenominal!!! You have inspired me to go ahead with my plans on doing a multi-diode setup for sure now. One more question: Does/did doing this require one or two wave plates? (one for each diode?)

Just one wave plate, two would bring it back to the + shape

If you ever decide that thing is too dangerous. I'd be happy to take it off your hands ;D

Seriously though that's some great work! Excellent job!

You plan on a 5-6W build with 9mm diodes?

A 5W build would be possible, but I don't think 6W is possible just yet, the optics loss is too high. Even if someone did build a 6W laser, the diodes would degrade really fast at that current.

I don't plan on building another though. It would be much easier now that I know what to do and what works best, but it took a lot of $$$ to build

Here's the real thread now: http://laserpointerforums.com/f65/worlds-most-powerful-handheld-4-4w-445nm-77173.html#post1109410

If I forgot to mention anything in that thread please tell me. I would love to see more dual diode lasers from other people, and I want that thread to be a good resource for others.

OMG HOLY SH!T!!!
you did it!
was really busy with school but when i came back today!!! :O
btw where r u studying now atm?
im at sfu
+1 for sure!
