[quote author=jayrob link=1223438970/520#533 date=1225480948]That's good information Igor... Thank you for that!
Jay

Keep in mind, i'm a very heavy user. Even if 200mA should be bad for it, it lasted several months by now. With normal use, the GGW 6x would probably last very long at this current..


Otherwise, now that i have some info on the new diode's electrical characteristics, i took another look at some datasheets. They never really fit any diode before... But what if this is the Sharp GH04P21A2GE diode? I used to think that was the GGW 6x, but the forward voltages are too high. The GGW has an unusually low forward voltage, compared to the PHR and the new 4x/6x diode.

But the electrical characteristics could fit the new diode. I wish there was a way to compare it to the power graph, but the power graph in the datasheet is the raw, no lens output. And we don't really know yet how much is getting lost with various lenses, while no lens measurements don't seem to be very reliable.[/quote]

You have inspired me to turn up my GGW 6X Igor. It will be your fault if it dies soon! ;D ...JK

Pretty happy with the FlexDrive / Meretith glass at over 200mW's...

191mA's and am getting 209mW's steady with the GGW diode and a Meredith glass lens.

The GBW diode that I tested gave me 163mW's at 192mA's in a Meredith glass lens. Over a 40mW difference!  

We need Amk to get the GGW sleds! (these GBW sleds are well worth it though Amk)

Very nice...

What does the beam of a GGW 6x look like after the Meredith, BTW? Is it still rounder than the PHR, when all of it is captured by the lens? I forgot to test this...

What driver are you gonna use?

As for the driver, a lava drive.[/quote]

Yeah, you need a proper dummy. Linear drivers can regulate the current through a short. You can put a DMM in the highest current measuring mode, and just hook up the driver to the DMM directly, set the current and it will still be what you set it to, when you attach a proper load.

If you're gonna use a FlexDrive, you need a dummy, and the dummy should be close to the load in Vf.

Not perfectly round...

But much rounder than an 803T. The dot is kind of oval shaped. But you cannot really notice this in the beam in the dark when turning the laser, like you can with the PHR...

Nice...

Since you're using the Meredith lens, you get to see the entire output, and not a clipped output, like with acrylics. Good to know the GGW remains oval with a high NA lens. Something to look forward to.

How does the 4x/6x compare to the GGW 6x and a PHR in this respect? Is it flat and distorted at the edges of the fast axis, or is it somewhere in the middle?

Re: 6x Blu-ray SLEDS GB! THEY ARE GOING FAST!

Since I sold my other GBW blu-ray in a Side Button Pocket Pal, I cannot do a close comparison right now.

But I did immediately notice when I first tested the GBW blu-ray diode, I thought that it was noticeably flat, just like the PHR.

Perhaps someone else could verify this. I could have been wrong, because when out of focus, they all look a little flat, and maybe that is what caught my eye when I first began my testing...

Yeah, that would be a good thing to know. I really hope it's not as flat as the PHR. And not just for aesthetic reasons! Usually, it is the weaker diodes, that have flat beams. The higher the power, the rounder the beam.

If you look at the 5mW diode in an AixiZ module, that one is so flat, it looks almost like a thin rectangle!

Re: 6x Blu-ray SLEDS GB! THEY ARE GOING FAST!

Lol! I've seen that red rectangle. ;D

How about it guys? Some of you guys that are testing these GBW blu-ray diodes... Would you say they are flat like the PHR's?

I never saw the beam and only had a brief exposure to the spot. The module sits in a heat sink that is the same height as the center of my calorimeter. No touching during the testing

I'll probably build a handheld this weekend.

Peace,

Re: 6x Blu-ray SLEDS GB! THEY ARE GOING FAST!

without the lens on it does look like a phr diode only the phr diodes ive seen look a little white especially pushed to high mA. these seem to stay purple looking. 180-182ma only gives me about 170mw.

You have a calorimeter!?!?!

Re: 6x Blu-ray SLEDS GB! THEY ARE GOING FAST!

Payment has been sent. I hope I get a good one. I'm looking forward to 200mW of 405nm.

what is the difference between a GGW and GBW?

one is pimper'er

;D ;D ;D

3 pages in a few hours?? Geez you old geezers do talk a lot ;D ;D ;D ;D ;D ;D ;D

lol

ok, so this is how it works: he said that until he sells all of his GBW's, he cannot get more GGW's. Also, he said GGW's would be substantially more expensive.

Re: 6x Blu-ray SLEDS GB! THEY ARE GOING FAST!

As do many others on the list. A calorimeter measures heat. Most people refer to this as their power meter's "head." A calorimeter measures the heat produced by a laser. It converts that heat into electrical information. The laser power meter (LPM), reads this electrical info and converts it into a form we can understand (numbers or a moving needle).

I have a Scientech 365 Laser power meter AND a Scientech 360001 calorimeter hooked up to it.

You say tomayto and I say tomahto

Good deal Mr. Sled!

Get the pricing! We will be on to those sleds soon enough!
Thanks!
