Blue laser 445nm

[Phritzler]

Hello!
I want to mix 405-457-473nm, so I want to use Laser-Wave 405nm Dichro to pass 457 + 473nm (which I want to couble with a semrock dichro... which will work?) and reflect 405nm. Does anybody test the laserwave Dichros with 457nm or 445nm?
Greetings,

IIRC, the laser-wave 405nm dichros will be pretty lossy with 445nm.., like 20% loss

There was alot of thecnical stuff to read here !!

but after 5 pages, is there any solution ?
My 2 Macroni red is DEAD now (I really dont know why, they only light 20%) !
But I need new red ASAP !!!

And in fact when I get more red, I think I need more blue also..
I have a deep blue now (200mW, from LasEver) !
Is there an option to add one more blue ? (in another wavelength?)

And my last question: What RED, and who sell it??

I really dont undertand about the macroni stuff (confused) !
But since both the lasers and macroni is "gone" , I need to find a new dealer for red..

So why is nobody making a sticky thread with the list of the BEST parts to buy !
3 lasers for a perfect smooth white !
And one setup for beam performance (bright laser in beam-show, but maybe not so "pure-white) ..


I hope you did understand my questions ?
As I notice there is some other newbies here that ask everyday where to buy, what to buy, what price, and so on..
Why not collect the best possible lasers from one dealer, and try to get the best prices in the same time?
Like Elvis say: Less talking and more action

That all has to do with budget and personal prefference.
There is no real 1 solutiuon fits all..

For red there are alot of "dealers" that sell great red lasers with nice beamspecs.
The problem is the price!!

I know that LASERWAVE (chinese company) is working on 645nm lasers.
Bridge told me that the beamspecs are going to make alot of people happy.
Knowing that bridge operates from china...the price will be lower than most USA/EURO based company's

maybe is wise to wait

Do you have a 457 nm laser? I guess you want all these different blue and violet lasers to expand the gamut. If so I would recommend just 445 + 473 and skipping 405. That gives almost the same gamut, but 445 is much more luminous than 405. Or better yet, 488 + 445 gives access to some amazing colors.

Hello!
I want to make a multiline laser , for use it with gratings.

Could you make "445" by mixing a little green with 405?

[tocket]

It should be possible, seeing as the line between 405 and 532 is so close to the 445 point on the locus of the chromaticity diagram. I have tried it in real life by mixing ~100 mW of 405 with a little green through a dichro and the results were unfortunately disappointing. It really looked like a mix of green and violet, rather than a distinct blue color. Low saturation and luminosity. Maybe if you have a crapload of 405 you can make an OK blue (I suspect I used too much green, but the beam still had low visibility).

tocket, Can you calculate what you get if you mix 200mW 405nm (6x burner) and 100mW 473nm?

[tocket]

You get 7.7 lm of what looks like 467 nm equivalent. The contributions are:
405nm: 0.63604 lm
473nm: 7.0772 lm

Coordinates in CIE xyz: 0.1392 0.0569 0.8039
