Does anyone even care about 473nm anymore?

I just have one question for you. What is 473nm? Is that a laser or somin? :crackup:

It's a measurement of wavelength, 445 nano meters, it refers to the colour of the laser.

Do a little more reading and you could have found that one out :)

Here's a little image I put together to help, its a modded visible spectrum diagram.

Now that 445nm is in and is very cheap, I just wanted to ask if anyone still cares about 473nm? I remember about 6 months ago drooling over a 5mW 473nm and I was so jealous of anyone that had one, but now i'm like f**** that there's 445nm and it goes up to 1 watt!

Blue has until now always been somewhat problematic: 473 is a very nice wavelength, but considering the price/mW it is also the most expensive color that cannot easily be made by mixing others.

I think the applications for 473 will be greatly reduced now that 445 is on the market at affordable prices - 473 dpss is still superior if you need the beam quality or its specific color, but other than that it will probably be obsolete soon: For projectors and pointers, the 445 diodes make a much better deal.

Also, i think 532 might suffer the same fate eventually, once green diodes hit the market. Since the dpss process for 532 is so much more efficient than that for 473, this might take a long time though, and they'll probably exist side by side for years in practical application.

I don't have a 445nm yet but i doubt that when i aquire one that my love for my 473nm
will diminish, its just such a great laser

I have a single line argon putting out about 30mw of 488nm which is a beautiful turquoise color. The 473nm beam from my old RPL blue-30 is more of a pure sapphire color while I'm guessing that 445nm would be more of a royal blue with a slight purple tint. *prays for WL to actually get me my spyder arctic sometime this year so I can see for myself*

Sorry, I was trying to be funny! (See the emoticon in my previous post).

Many of us collect wavelengths. I will not rest until I have them all.
There is more to lasers that just burning stuff.

I agree with this, next for me is orange or yellow, and I love the perfect tight beam on my DPSS 473nm blue, it's beautiful. I don't like how sloppy most diodes are, my dilda has scatter and my violets are pathetic to begin with, even a cheap and poorly aligned green is better than any diode I've yet to see.

473nm is a pure blue laser

lol i was just thinking that too

473nm is the best wavelength ever

Dang triple post! I love my 473nm lasers. I wish that I had a 1200mW 473nm instead of a 445nm. The color is more blue and less violet. It is weird, when looking at 445nm the spot looks pretty blue but the scattered light around it looks violet and many surfaces. Even the beam looks more violet compared to the spot.

why couldna casio buy a cargo holds o' 473nm instead o' 445nm i guess on accoun' o' 't would cause problems but 473nm be better me hearty has a 5mW 473nm an' cni sells a 13W 473nm I`d be lily livered t' e'en eyeball th' beam on that

473nm DPSS lasers don't work anywhere near the same as 445nm laser diodes. The differences (size, heat generation, complexity among others) mean that 473nm lasers would never be practical for use in a design like the projector the 445nm diodes are being harvested from.

I have a thing for DPSS lasers.. I'm fascinated by how they work. I'll never part with my 473nm lasers, and I might buy more..

I have replaced the 473nm laser that was in my full-color projector with one of these 445nm diodes at 620mW, though.. The color depth has improved greatly. They are far superior for laser show projector applications.

I like DPSS too but th' thin' that I do nay like about DPSS lasers be that they be havin' lots o' problems (EX: Mode hopping) an' that`s why diode lasers be better but DPSS seems prettier.
