UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU WIIIIISSSSHHHHH!!


im going to order some Pr now...and then going to...u know...do stuff

You people do realize that any emerging display technology using these will likely initially be very expensive, plus only have ONE (1) white light or one of each color laser right? They won't be like the projector scavenges where there are loads of lasers in one device. This will mean that most likely, the cost of said lasers will be in the thousands of dollars, since you only get one, or one set of each color, per device.

if the a1x0's only had 1 445nm in them instead of 24.. the cost for the hobbyist for them per diode would be about the same as the projector cost.. >$600, instead of the $35-$50 we have now.

I do think this is an awesome technology and the hobbyist community WILL get lasers out of things with them hitting the market.. I just doubt they'll ever be 'cheap' lasers.

Ney Sayer! -GH

1 diode per projector seems too less...unless it was like 30W or so of power...

How so? the pico projectors work without loads of diodes. I imagine most new devices will be scanning beam as well. That requires a lot less power than DLP, etc, which wastes a LOT of light.

Plus these aren't diodes we're talking about either. they're a new type of DPSS.. They're inherently going to be larger than diode lasers.

^ Yes, but afaik, the more illuminating single-diodes picoprojector, actually, is around 120 lumens max total, not around 2500 / 3000 .....

If they had used a single 30W 445nm laser source, DPSS or not, you don't think it may worth also dismantle 600$ of projector, for get it in your hands ? .....

they will be much different (although i dont think that much different from our greenies) but in the way that they have lots of them...they just have to get the process cheap enough...

and they need power...and by what i read (might be misleading though) they havent had more than 40% efficiency for any line...only 40% for red, then i think its green and then the others...see a post i made above with the efficiencies...

so we would definetly need more than 1 diode per projector...or that or a bulky gigantic faser that would completely ruin a normal size projector (although it would look good on the mammoth sized ones )

Some would, but look at the ever increasing population here that complain about $40 445 diodes being too expensive. I think the number of people on this forum who would actually pay $600 is fairly low.. Even for 30W... though I don't really think they'll be that high powered. Plus i'm sure the beam specs would be godawful too.

for a DPSS laser?? how can the specs of a DPSS laser be aweful? compared to an injection diode?? beam specs are neat!

and of course they wouldnt be high powered...there would be more than one

i'm talking about the theorized 30W 445nm pump, which is what HIMNL9 mentioned.

aahh!

as this thread is about the Pr doped stuff, and the main thing was to get a white DPSS laser, i thought he was talking about a 30W output laser on the white range...

didnt notice he said the pump diode

even so, my point is that they would get modules of a Pr doped thingy in a system like our greenies and have several of them...unless the structure of the doped glass would be enough to accommodate lots of power...then maybe they would only have 1 glass and several pumps...

He didn't say pump, however since this Pr3 material is getting pumped with 445.. I can only assume that's what he meant.

Though for display use, the actual wattage wouldn't need to be nearly that high even for the Pr3 stuff. Projection would need higher wattage yes. But TV's and things of that nature generally only need about 1/3 the light power of a projector. And that's just for DLP. A scanning beam configuration would need even less power, since less of the light is 'wasted'.

Though at any rate, everything right now is just a theory. It will probably be a few years at minimum before any laser based equipment using this technology hits the market, at any price.

True, TV and similars needs much less power, but this, ofcourse, is caise you are looking at the source of the light (screen, plasma, OLEDs, etc) ..... where instead in a projector, you look at the reflex of the light source, and also spreaded on a larger surface ..... so, the apparent brightness is much less than when you look at the light source directly, and for get a decent level of luminance, you need much more power.

different is the case of a "raster scan" type laser projector, where the laser beam make the image "scanning" the horizontal lines, like the electron beam in a standard phosphor tube ..... this may require less power, but for the counterpart, we still don't have scan projectors that can obtain decent results with this system (yet).

@ LordKaramazov: you're right, sorry, we have derailed a bit the thread original topic (but, after all, isn't for this reason that topics exists ? ..... for become first or after derailed, i mean ..... j/k )

Staying (almost) ontopic, no, i doubt really that they can use a similar multi-wavelenght system for a projector unit, or for something related to projection, at least in short times (some years, i mean) ..... it does not seem having too much efficence, compared with "standard" RGB lasers systems, imho ..... at least, at the actual state of developement.

the whole point of doing a system with this laser or similar wavelengths would be to get a wider range of colors, and in the end a much richer picture...

and yeah..those 445nm from nichia took around 5 years to get to us...id say this one would even get more. They had the first doped stuff pumping in around 2006/2007...but we can only have faith that the industry will actually take this stuff to a marketing level
