AND..? :confused: That's it? :(
Hi Dave,
The power supply says operating current is 472 mA. It's got another parameter that says 1.34W/A. Is that thing putting out 630mW?
What's the price?
Tim
Marconni !!!!!
GET THESE ( If beam dia and divergence are OK ) ===> Double like the red...looks like mw may be max 150 from Google/Nichia Blue Laser Diode info ?? MTTF ???? Unit Cost ??? CHEAP BLUE ??? Wu Wu !!! Wada Photonic
" Hydraulic Dream " !!!!!!!!!!!!!!!!!!!!!!!!!!!

Hello!
What Price was for the diode? What Optic do you use to colliminate these? What driver do you use?
Thanks,
Phil
I think its doing about 250mw. Peak is around 500mw.Quote:

For those of us (me) who are not experts in laser technology; what am I looking at? Is this just a diode? Why is the package so much smaller than a 473nm ? This sure looks like the blue laser I would want to use.
James. :)
This thread is an amazing tease...
... a kind of suspense thrilling story ...

Thats very nice, Dave! How does it compair in apparent brightness to 473nm?
IT looks beautiful in top picture, almost like you've put a solid blue perspex bar across. Certainly doesn't look like light.
Nice colour as well, maybe a little light for some tastes but nice never the same.
It's a direct injection blue diode - just like the 445 nm Nichia diodes. (The one's you see in those lovely Arctos projectors!)Quote:

On the other hand, I'm sure they're every bit as expensive as the Nichia diodes, which means they're *way* out of my price range...
Still, I gotta admit that it's fookin' beautiful!

I really want to get everything mounted properly and mixed with red and green to find out :) Those pics were taken with a bit of haze in the room..

yeah dave, how much are they ?
and the Price is ..... " Dave will be right back after the commercial break "
doh..... :D
all the best ... Karl
it may be a case of if you need to ask - you cant afford.....
Gorgeous colour though :)
Rob
About $3000usd ea for small quantities.
Its a pity the digi cam doesn't pick up the true color tho :(
Visit HB-Laser:
400mW with Analogue Modulation cost about 2152€ in Germany. The Mixingcolor is very great and you got a awesome white!
800mw 4392€. The Beam isn`t beautyful as a DPSS Laser.
Dave ....
Have you won the lotto .... and bought 4 of these diodes and a mount :D
:eek: Good eye!!! :cool:Quote:

$ 3000 USD per....That's crazy !!! Why so ,so much $$$$$ R & D ...Yeah...right.......Because they can !!! I assume the unit/$will drop lika rock in production manufacture ??? Might as well " Bark at the Moon "" right ??? !!! Anyone have any insight into such a price policy ????

I think it really comes down to how many are made and how many of those actually work. I bet the numbers are no where near those of other things like blue ray units. If there is a common, consumer type need for these things, then they will become dirt cheap.Quote:

Thats about it eh.
However laser tv might do something to bring the price down I guess..

That's easy! When there is a whole factory full of people making thousands of units every day!Quote:

You can buy a dvd player for £18 and the cost of that includes not only the laser but the casing, the tray mechanism, the motors, the transformer, all the other electronics. Which kind of leaves me figuring that the red laser module inside is costing probably less than a £1. Try and buy a powerful Red Laser module for that!
For a Blu Ray Player, you can buy a computer based Blu Ray player for around £150. Most of the additional costs are listed above under DVD. So again the Blu Laser module whilst more expensive is clearly costing only a few pounds (remembering that the retailer usually has 100% mark up (price £75), distributor 100% (£33), importer (I would think similar (£18)). Which kind of brings us down to a TOTAL component cost of less than £18 less import taxes and shipping costs which in turn probably brings the laser down to around a pound or two. Yet try and buy a Blu Laser Module and you're looking over £500, possible in the thousands. Even if I got the mark up margins wrong, you're still talking in the low tens of pounds.
alsone;
You're confusing the cost of a blu-ray player (low power diode - maybe 10-13 mw tops) with the cost of a blue ray *BURNER* (50 mw and up).
You can buy the entire PS3 laser module for around $30 on the Internet. For that you get the blue ray player diode (405 nm) , the DVD player diode (660 nm), the CD player diode (780 nm), plus all the optics and all the mechanical parts that make up the sled. Pretty cheap price!
Now, if you (carefully) take that module apart and harvest the blue-ray reader diode inside, you can build your own blue-ray laser pointer. It will make around 10 mw. (Whoopie...) But know that you can kill the diode *very* easily. Most people buy two or three of the sleds just in case. (I've personally killed two of them so far.)
Contrast that with the cost of a blue-ray burner... Last time I checked, those things were selling for around $500 or so. I've heard talk that you can buy the bare diodes that go into the burners for around $150 or so, but I haven't seen any links. And even so, those diodes are only good for around 50 mw or so. (Well, again, I've heard that some of the newest ones can be pushed to around 90 mw or so, but I haven't seen any proof yet.)
So there's your price difference. If you want a pre-packaged solution that you can unwrap, plug, and play, then you're going to pay extra for that. But if you're on a budget and are reasonably adept with both a soldering iron and a drill press (or better yet a milling machine), then you can just buy the bare diode, wire your own driver, and build your own mount for it.
As for the $3000 price tag on the 443 nm diodes, well, all I can say is that they're brand-new. The price will probably come down some, but as others have already mentioned, there is no "killer ap" that uses these diodes yet. The laser show industry alone can't provide enough sales volume to push prices much lower.
Now, if they start using these things in lots of consumer products (laser TV, laser cell phone displays) then the cost could drop by a factor of 10 or more. I'm not holding my breath though. (The Nichia 445 nm diodes have been out for several years, and they're still priced in the stratosphere as well - mainly because they're a lab curiosity outside of the laser show biz.)

Hi Adam,
There's a Blu Ray Writer here for £155 (I thought I'd see one).
I appreciate that the modules in these instruments aren't exactly the same as the modules you'd get in a proper laser module designed for show use, but the fact that they obviously can be produced cheaply seems to rubbish the idea that its expensive manufacturing processes alone thats making laser entertainment modules so expensive. At least thats my take on it.

I suppose you can have all the same arguments in the medical industry ...research and development costs !!!
With no ready market im pretty sure they will be trying to recover some costs in the first few thousand units .. like anything if it goes mass production !! prices will hit the floor ....... the first ever green laser pointer i saw on sale was $1000 , the first ever Blue laser pointer $2000 ..... and prices have dropped hugely in the last 3-5 years .
Looks like handy bit o kit !

New higher power 6X blu-ray burners are 250$ in the US. Made by LG.Quote:

LG got a hold of a VERY large batch of 6X burning diodes. This is a pretty damn good deal.
problem is the blu-rays are 405nm, not 443. I don't think 3000 is really too high an asking price at all, considering how powerful the things are, and how much it costs for 1/2 watt in 473nm dpss of the same reliability as a simple diode based system.
Da2001 mentioned erlier in this thread about HB laser
well ive just had a price list emaiiled to me and they are doing 20% off thier standard pricing ....
and as Da2001 said the prices are very good seeing its a complete module with cooling etc ...
half a watt of blue for £1700 uk pounds aint bad
and im sure prices will drop .............................. eventualy :)

all the best ..... Karl
thats true, but remember that you will need a lot more power as 473nm.
405nm Diodes are not usable for Lasershows. 150mW is for your eye like 5-10mW 473nm.. But you can build other beautiful colors with it!
If you see the beam or a spot, it`s like your drunk or like wearing eyeglases of an old man ;)
2 friends of me got the Blue HB Laser. The lasers are very nice, but don`t forget the Beam Quallity. Its not a single Diode like an DPSS laser..
