[rog8811] sent in this really cool hack where he used the optics sled from a PS3 as a foundation for a 7 color hand held laser projector. Combining a green laser, a blue ray laser, and a red laser, he is able to produce a variety of color including white. There are step by step instructions on how to make a multicolored laser. He then goes even further, showing how to integrate this into a hand held projector with pre programmed patterns. You can see some examples of the different colors and patterns in this video.
Video no worky.
video worky just fine, aj. Flash plugin much?
It didn’t work for me the first time eigther. Try refreshing it. I think its just metacafe being moody.
That’s some powerful optics ju ju right there. wow.
super major
video worky fine here.
NoScript will keep the video from loading. Temporarily allow ‘mcstatic.com’ to allow it to load.
Me Likey… That is a really nice compact design..
COLOUR > COLOR
Wow, thanks for taking this up :) If you want any further info I will be pleased to answer any questions.

It is nice, but not truly a LASER.
LASER is by definition a coherent
source of collimated light.
While the light is still collimated
after mixing the three beams, it won’t
be coherent.
Anyway, the white beam is beautiful and
I doubt he would like to use that for
some serious applications.
So, nice job! The three beams looks to
be very well aligned, I must admit it
is difficult to do that with that size
constraints. I have to use expensive
lab optics and supports to do the same
thing.
Very nice :P
I like the creativity of combining “salvaged” electronics.
I noticed the ©2007 on the website roger, how long did it take to construct this ?
Again… Very nice.
:)I only noticed the date after constructing the web pages, the laser and the website all put together in December 2008.

That is really cool, ‘scept I kind of think it might void the warranty on the ps3 to do that.
Impressive Young padwan. Your skills are getting better every day.
I wonder if you could use this for DIY Color Holography….
I don’t know much about laser diodes, but can they be hooked to a PWM? If they can, couldn’t you get WAY more colors with that setup?
@EllisGL
No, you can’t. Like I said above, the
white LASER beam is not coherent.
You would need a phase modulator to
correct the phase of the three beams.
I like this alot!
rog8811:
Nice Setup and nice job on the alignment. It looks really good.
For everyone else:
Hey! You can modulate them you just need different laser diode drivers.
The white beam is still coherent … just 3 different coherent beams in 1 space. Your eye mixes the colors and shows you white.
If you used PWM you would need to use a really fast modulation frequency and/or maybe a DC filter on the output… as soon as you move the beam around you would get dots instead of lines.
You can buy the PS3 Laser Sleds as a replacement part so you don’t have to take apart your PS3.
maybe some of the fibre channel stuff would be a good place to look for a rough pwm design, i’d imagine a commercial product would need to be able to switch really fast.
Can one purchase this laser from caleb kraft? Or atleast communicate about this amazing laser?
