I didnt know you were a noob?

It is what it is- three 5mW lasers w/ PS and the dichros to combine. What are your doubts. You cant buy 3 5 axis mounts for 125$ . This is a kit for the newbies! duh!

Well, what surprises me is that there don't seem to be mounts of any kind.

I don't see how it would be possible using only this kit to create a white laser, or at least combine the three included lasers into whatever color results from their actual ouput. How are you supposed to asseble this? Tack everything to the table with chewing gum and hope for the best?

...I'm sure it includes the mounts, lol. They show circular dichros, not square, so they couldn't reasonably be expecting you to mount them to a flat surface on your own. They're selling this as a "kit" and it's quite pricey. So I'm sure Aixiz is including the mounts.

1. They're careful about not using the word "white" or showing a white beam. Why?
OKay- the notion that some semblance of a 'white laser' could be made came entirely from me.

2. Where are the pictures of the dichro "lenses"?

3. Why are two phosphor disks in the picture? Have they confused these with dichros?
I dont think the are phosphurs.
4. 5mW reds are usually 3mW, 5mW greens are usually 10-20mW, and 5mW blurays are usually 30mW+. The picture seems to support this.

5. Good luck aligning the beams without mounts

Very true- I look at this kit as simply a way to get the feel of beam combining- IMHO anything that takes somebody from pointers & handhelds to RGBs is a good thing.
6. Their "power supplies" are just modified phone chargers. Sure, they'll work great, but... $125? poor newbs

I'm not sure but I think these are a bit better than 2$ wallwarts- maybe a better regulated type or whatever.
I would never pay more than $1 for a used cordless phone charger- I routinely recycle them and only get 10cents a pound for them.

7. What these cost separately on ebay: $4 for the red, $9 for the green, $11 for the blue, $2 for the phone chargers, and $33 for the white and red phosphor disks for a total of $54 + shipping. And if you buy them all at once, you should get a 10-30% discount.

I never saw this kit as some kind of super deal. And I certainly would not want to see any noobs get taken advantage of.

I am fairly certain that no mounts come with it. A piece of a 90 degree Al can make a crude mount.

I don't see how it would be possible using only this kit to create a white laser, or at least combine the three included lasers into whatever color results from their actual ouput. again the white laser part came from me-not AixiZ. If you feel better calling it a RGBr then fine. What else would you call R+G+Br ? Off -white?

My OP more or less addresses all of this.

How are you supposed to asseble this? Tack everything to the table with chewing gum and hope for the best?

NO MOUNTS!!! I repeat--NO MOUNTS - you need to DIY or get inexpensive ones like the ones in the attachment. I have seen a youtube vid of a rgbR made on the cheap using Leggos. EZ to align? HARDLY!!
But still a good learning experience that, at the least, will give one a greater appreciation for REAL mounts. Crawling always preceeds walking and running..

Re: white laser kit-RGBr-from AixiZ

Well, i suppose you can use rudimentary mounts like these: RGB laser systerm lens holder/frame/2pcs in a pack [OLRGBF] - $7.99 : Welcome to O-Like.com, Your source for laser products

You'd need to fashion one additional degree of freedom to make it usable, or get your lasers on ajustable mounts to get it really workable, but at least its a start. Given the dichros to fit those mounts are only $25 a pair, i'd think that is a better deal to start combining colors.

Re: white laser kit-RGBr-from AixiZ

The kit is pretty lame by laser hobbiest standards. Still, it's probably directed towards teachers or people who just want a "kit" and not bother with making anything special. I guess there's no shame in catering to that segment, even at outrageously high prices. Reminds me of Apple users, though that seems to have changed somewhat over the years.

thats easy the boys wear blue booties and the girls wear pink. ya big dummy!

so those five baby are worth a bid handful of $$-- good thing all you have is the photo.

btw- flat bottom-male
concave -female.

I may be far from my specialty here ... but I thought it was the other way around, easier mounting... think about it.

from wiki

Normally, the bottom shell is a female turtle is flat, while the male turtle's bottom shell curves in a little.

^^^^so Glenn you are correct I had it backwards- Im slipping in my old age.

Re: white laser kit-RGBr-from AixiZ

I think this is lame too. (not trolling) For $125 you can buy the better parts to make a white, or at least close to, a white laser.

BTW Male turtles have long front claws to stimulate the back of the females neck to get her horny. I've had a turtle for over 15 years now.

Well, it should at least mention that it is not feasible to build a white-ish laser setup with only the components included in the kit. Aligning stuff with limited freedom mounts is bad enough as it is, but without any mounts its downright impossible to get a stable setup.

Re: white laser kit-RGBr-from AixiZ

It may or may not be lame - but at the end of the day, I'm not sure it really matters.

I feel like anyone who is at the stage of familiarity with lasers to be thinking about building an RGB white, is going to have the knowledge to see why this kit isn't for them.

If anything, I think this is a kit that may not sell well - it may not have much of a market. But I'm not sure it's any great travesty that this product page exists. I'm not sure anyone is worse off for it - I just don't see it appealing to a whole ton of people.

Re: white laser kit-RGBr-from AixiZ

Sorry if I gave the impression that AixiZ was selling this kit as a way to make white.

And I cannot disagree that one could get three cheap pointers for less than 20$(but you would need to observe a much shorter duty cycle) and some semi-usable dichros very cheap from sleds and ca5io projectors.

The modules that come with this kit can be gotten singly for about 45/50$ total and the wallwart style power supplies for another 40$. The dichros that come with the kit are not cheap so if you total it all up the price of 125$ does not seem to be so unreasonable.

I still like the idea of finding something cool to do with lasers aside from burning balloons and popping matches.

AND.... Even if one could only get the three beams close together it would make for some nice lumia and spiro efx.

I think you missed my post, mister hakzaw - specifically numbers 2, 3, and 7.

hakzaw1 said:

Why do you say that? These have no more heat dissipating capability than that of a pointer. They're also low enough power that they don't need a duty cycle anyway.

Len the title says "White laser kit". Impression is an understatement. :tinfoil: BS would be the proper term here.

I'm betting this is more for teaching how light can combine to make other colors using lasers, mostly to make a white dot on a wall, not really a nice beam. Some people will probably attempt to make a white laser beam by gluing and fussing about with the alignment in an incredibly frustrating experience that may appear on Youtube.

In the end, this product seems like an expensive and lame "kit" being marketed to ignorant people for a cheap buck. If Aixiz are going to charge these excessive prices, they should provide a professional teaching kit, with experiment instructions, mounts, etc. Aixiz's kit is a rip-off, plain and simple.

hakzaw1 · May 12, 2011

Re: white laser kit-RGBr-from AixiZ

I have changed the title. my bad.

however if you will read the OP you can see that I did not make this 'kit' out to be more than it is.

and there is definetly a short duty cycle to green pens and I did say that a DIY heatsink may be needed for these modules.

dichros-NOT phosphurs

Cyparagon · May 13, 2011

How can you be sure? They picture phosphor disks. Some intern probably screwed up the terminology when writing the description.
