Magenta / cyan

Are magenta and cyan lasers as 'easy' to make as yellow? What's the ratio? How much power is lost / gained in the combination? What if I add yellow + magenta, or Cyan + Magenta, etc? Or (Magenta + Yellow) + ((cyan+ Magenta) +yellow) etc. I'd have no problem with an 'array' of like 12 lasers (granted it'd cost a ton) to get some pretty cool colors, plus 500+ mw's from them. Just a thought.

Ehm ..... a bit of reading may have given you most of the questions

Anyway ..... first, you can combine only a limited quantities of beams, due to the problems of the combination systems .....

As example, with a PBS (polarized beam splitter) you can easily combine 2 beams, one polarized in horizontal, one in vertical, so, 2 BR, or 2 red, or a BR and a red (that gives you magenta), but at this point, you cannot add other beams to this one using other polarizers ..... with dichros, it's the same, you can combine 2 different wavelenghts (one pass and one reflect), but not another same wavelenght beam with another dichro .....

With 2 dichros made for specific wavelenghts, you can combine 3 different wavelenghts ..... but if you have a beam that is already made with 2 wavelenghts, like cyan or magenta, the third one must be different, otherwise part of the combined beam become reflected away ..... and so on .....

Otherwise, you need special dichros, but i think they still have insane prices .....

BUT, it's possible?

Sure, it's possible, however the optics to combine that many wavelengths aren't really available, you have to get them custom made.

SOME combinations are possible, but not all.

As example, if you use a PBS, you can combine OR two diodes from the same wavelenght (red or BR, as example) for double the power, OR a BR and a red, for get magenta ..... but, if you use them for combine two BR and two reds, then you must use a dichro for combine them together, cause the polarization now is no more single plane, so another PBS don't work ..... same with the green, that most of the times is not polarized, so you must use a dichro and not a PBS for combine it with other colors .....

And for the dichros, they can be built for different wavelenghts, but not for all (must have some distance between the different wavelenghts, otherwise you have power loss) .....

And, ofcourse, cannot be combined more than 2 diodes from the same wavelenght, and only with PBS, cause you can build a dichro that pass one color and reflect another, but ofcourse you cannot build a dichro that pass AND reflect the same color

why open a new thread :thinking:
you already opened one for making a yellow, why not add questions to the old thread?

Or you could get the White Fusion kit and have all those colors, plus others (including white).

Took the words out of my mouth.

Do some more reading Bloom.

I'm not the one that needs to do some more reading, I know of the white fusion. I was saying things like yellow + cyan, magenta +yellow, or what magenta + yellow makes , + cyan. Get it? Not red + green + violet. Not to sound like a grouch, but it seems as though either what I'm trying to do isn't possible, or people don't know what I'm saying, or both. I get now that if I get yellow, and try to combine it, it will uncombine like in RGB projectors. But there must be a way. Maybe the following would work:

Yellow is made, AND magenta is made, both on different parts of a platform, then the yellow hits a mirror, and so does the magenta, they are then reflected into another 'system' of one sided mirrors, the mirros they get reflected into make a 'V' shape, the outside of them isn't mirrored, only the inside, so they pass the first one, then reflect into a 90* angle. Both the beams hit the VERY bottom of the 'V' so that they almost, but not really, merge, so close that it looks as though they are in one beam. Like two toothepicks next to eachother, but overlapping a bit. Then, (now this part sounds a bit 'fishy') they go into a 'funnel' of mirror (like a reflector from a maglite, yet a LOT more of an acute angle), to make both beams go through the same point, about 9/10's the size of the original 'beams' so that they bounce off the edges, and HAVE TO 'merge'. That's my idea, it sounds like it won't work, but I want to try anyway, and hey, if it doesn't then I'll just take it apart and make something else with them. But, if it does, I will then try to merge cyan with it and try to get a pure-er white.

Yes. You are.

yellow + cyan = Green, magenta +yellow =Red or what magenta + yellow makes , + cyan =White. Get it? Yes. But you do not.

It's not us, it's you. You need to do some reading on additive color mixing:

Try it, and let us know how this works out for you. :crackup:

If you REALLY want to combine the exotic colors like yellow and cyan, BUY a freaking yellow laser at 589nm or 594nm and BUY a cyan laser at 488nm. Quit trying to do weird stuff. This isn't a cheap hobby, and if you DO try to do it cheap, you'll waste so much money that you may as well have just done it right to begin with.

....word. :beer:

How about this: It can be done - White laser pointer

I don't think you'd get much power from it, but it looks like it can make the 7 colors (and you might be able to make many more perceived colors by doing PWM mixing of the 3 lasers).

I don't have $500+ to spend on something I can MAKE for only $100....and if people didn't do wierd stuff, you wouldn't have lasers to begin with, so don't yell at me just because I want to experiment, people like YOU told people not to do 'weird stuff'back in the 60's, lasers were considered 'weird stuff' back in the 60's but one was invented, and look where we are today. Just because I want to try something weird doesn't mean you have to be rude about it. And if it doesn't work, and it probably won't, then I will just take it apart, and make some normal yellow, magenta, and cyan lasers. Maybe I want to mix white and yellow, or magenta and green. Whatever, I want to do it, it's my damn money, my damn project, so don't just tell me, "Just buy it" because that tells me that you don't want me to experiment, I won't figure out the science behind something by just buying it prebuilt. It may cost more to build it wrong than to buy it right, but hell I don't really give a damn, I want to experiment and I'm going to. Good day sir.

LOL

Sensitive much?

Do what you want breh. My only point is that the experiments you're speaking of have been tried a hundred times here, and have mostly been proven not to work. If you wanna mix green with magenta, get the white fusion kit. Why mix yellow and white? In the white fusion kit, yellow IS white-violet. Adding more yellow to white is just yellow.

Good luck either way...

I'm not sensitive, just irritates me when somebody's main leg to stand on when somebody proposes an idea is 'Just buy [final product here]'
