blu ray player laser pointer image
Flaming Le
what colours can a laser pointer come in?
and which are the most powerful(in order plz)
cheers :P
Answer
Commonly, Red then Blue then Green. Red is the weakest, green the strongest.
You can get a red pointer anywhere. I haven't seen blue lasers commercially available but they're a part of a blu-ray player so you could probably transplant one to a pen if you hacked it. I've seen green lasers available for order as the most powerful lasers available to the public, but they aren't particularly cheap.

School project - help laser pointer?

I need to make a some object that shoots out light... therefore a laser.... lol but anyway
I need step-by-step instructions on how to make a fairly easy laser. I know you need a diode from a cd player but I need instructions on how to attach the wires and other things... I plan on buying the parts online.
I want to know how to do it and plus if I make it out of nothing and retrieve the parts and put it together myself I have a sense of accomplishment
Plus it'd be way cooler than buying one... more fun...and no one else in my grade could begin to make a laser pointer

Best answer
as long as you DO have to put it together
Answer
cd diodes are IR so you will no be able to see it. If you own a digital camera and it doesnt have a IR filter you would be able to use it to see the light.
You would be able to see a blueray diode but they're not easy to come by so you would have to buy one off ebay
The main problem with both is the lenses on the lasers are focused around inch away from the diode to read/write on the disk. There by they really dont look all the much like a laser but more like a led.
You can buy something like this
http://cgi.ebay.com/150mW-405nm-Blu-ray-Blue-Violet-Laser-Diode-Module-Kit_W0QQitemZ270430046283QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3ef6e3084b&_trksid=p3286.c0.m14&_trkparms=65%3A12|66%3A2|39%3A1|72%3A1205|293%3A1|294%3A50
Comes with a diode and a driver that would have to be wired up. There are other kits like this that are cheaper if you look around.
