who wants to tame this?

Probably going to drop steadily, but not plummet. If you had a dozen of these you would sell them for as much as you could and the price of comparable power from DPSS lasers would be the floor. The advantage of direct diode modulation against the hassle of beam correction/combining and diode driving might be a trade off.

Its a good time to be alive.

We need to do a murder fund. I'm in for $10.

I think you definitely hit on something there, Steve. IF projectors could be had for that price, which I am willing to bet they are going to be in the $900~$1500 to cover the R&D for the first few years, we are not going to get these diodes for under $100 from tearing apart a projector. In fact, I have a feeling the 445s may go up in price as this becomes more prevalent since there won't be nearly as many needed to produce the green from the phosphor wheel.

I doubt they will go up in price. What will definitely happen and is already happening is, that they will go up in power AND emitter size. The last thing will probably render the next gen diodes unusuable for laser show projectors, unless you can live with several mrad divergence.

Never mind, seems LPF is already doing one. http://laserpointerforums.com/f55/gb...way-86766.html

This greatly effects your future, and the more info the better. I'd think you guys would be more proactive with things like this. Or is it "private" info only? I'm still trying to get a reading on you lot.

Its easy. Everyone chip in, test it, pick a number out of a hat, and make everyone happy.

These will most surely go down. IIRC the first 445nm diodes were selling for well over $500.

[planters]

At $940 I'm not ready to start being proactive. I think this would be more like jumping the gun. I rarely keep secrets and then I just don't talk about it. Other than cold fusion... Anyway, why do a murder fund? unless a diode could be relied upon to produce 3-4W it just isn't competitive with DPSS yet. And, at this price no one is going to want to take the chance to so over drive this diode. The LPF folks can't put a watt level DPSS in a small flashlight and so the appeal. This current price is just a deal killer. I predict these will begin to be studied when the cost hits $500 each.

Since the 13th they have raised 640/880. You guys have way deeper pockets than LPFers.

Maybe the wattage is not comparable to DPSS, yet, but the stability is far better. Plus I'm sure these can be pushed easily over the 1W recommendation. Throw a cube in there and get ready to throw away your DPSS system. These are great for projectors because the beam can easily be corrected, plus they will have simular beam specs with the 445, and 632, so no more halos.

This is a very big deal for you guys. Yet a juvenile laser pointer forum is leading the way in testing so they can make a pointer out of it? You guys spend 10's of thousands of dollars on projectors, but no one can chip in a few $$ to test something that could change your hobby forever. Doesn't make much sense to me.

Sorry, I was not implying you were keeping secrets. I do know some people like to horde info for whatever their reasons are. We had a few on LPF, and they were quickly excused from the project. My belief is info furthers the hobby for all, and holding back info for elitist reasons is shallow and degrading. Once again I'm not saying this about anyone, I dont know anyone here personally, its only my personal belief.

i have no interest in pointers, but if you've ever compared PCAOM modulation to DPSS, you'll know exactly why i'm hopeful.

Exactly. You told me that your best modulation can only be achieved from your slowest DPSS. Plus, when these come down your W/$ ratio on green will drop 10 fold.

Its funny how LPF is looked down on here, but there is clearly more chatter about this new diode there than here. Personally I'm hugely excited. And not for pointer reasons, LOL.

[absolom7691]

I think one of the big things that you're missing is that, while the modulation on DPSS green is not too reliable, they are reliable enough and they are certainly cheaper, by a lot! The other thing too, is beam quality. Diodes will never reach the beam quality of a well built DPSS. As Eric was trying to say, you can't get 1+ watts of green in a pointer. This is the reason LPF is all over this like crazy. Pointer guys don't care as much about divergence, beam trash, things like that. At PL, we are trying to get our projectors as close to ion quality as possible and that takes money.

About elitism, there is nothing elitist about waiting for a few facts to surface before spending a ton on something unproven which is way more expensive and and may lack the quality of what we already have. Modulation stability is very important but beam quality is more important. We like value too. This is why we have money to spend on big toys!

.

The beam is easily corrected, please show us your lens and correction lens info, or is this your speculation?

I agree with ya actually did chip in, but it isn't a murder fund just informational diode won't be killed.

Also have been hugely surprised by the knowledge I have found over there. My meter will now have logging thanks to delta ISIS and peregrine.
