You can go to radio shack and buy a 65$ green 5mw green laser.
Or you can buy violet lasers, blue lasers or red lasers, and redish orange lasers.
Or you can spend a decent alot more and get whats called 7 color laser it has all the basic mixed RGB colors.
if you are looking for a laser pointer then this might not be the right forum. ( http://www.laserpointerforums.com )
if you are looking for a laser projector then this is the right place.
What are your intentions with the laser so that we can help you further decide what might be the best laser for your needs?
also keep in mind especially as a teacher with either a pointer or projector to keep safety priority no. 1 (never point at living object) :)
If you're using a laser pointer for its intended purpose (hey, that would be a first!), that is, pointing out interesting stuff on a screen, you need something that is fairly visible and still eye safe when used more "irresponsibly", e.g. causes no trouble if a non-laser-literate user decides to wave it around randomly.Quote:

Other wavelengths (445nm blue, 638nm red) are nearly impossible to see with a low power like that.
Do pay attention to cheap Chinese copies though -- they tend to have a slightly higher power rating than what's on the sticker and some of them lack an IR filter.
Obvious troll is obvious... has he said anything about WHAT he was teaching or even if English was his native language? Not everyone is from the English speaking parts of the world. ;)Quote:

You mean that in some languages they don't use a capital letter to start sentences?Quote:

Or proof read their posts prior to hitting the SEND button?
And these are the teachers !?!
That's some crazy shit right there, Man.
No wonder da kidz of today can't communicate via the written language (nles its txt spk).
Is this for teaching Physics and English is not your first language?

just use it as an pointer at my classQuote:

Keep it below 5mw in power otherwise your children could be claiming for eye damage from a stray point (you should avoid pointing at them in any case even with 5mw but accidents happen and at least 5mw is considered to be usually safe). You also need to consider the laws in your country to check that even 5mw is allowed. In the UK I think the recommended power on pointers is now 1mw, although I don't think the limit is not mandatory.
Also, as Marc said above, choose green as its the most visible colour for any given power.
I know this post is too much old but my reply will help to new seeker . Here I would like to top rated 10 laser pointers that professional can use in meeting or class rooms.
check now top Rated Laser Pointer
Well, I would recommend you the 'DinoFire Laser Pointer' because i personally used it and is pretty awesome. you can check more best laser pointers for presentations.
wouldn't a key chain laser or pet laser work for this? there under 5mw extremely low cost, available every were including dollar stores and for the price you can supply every kid in class with one so they can focus your attention on there point and matter making safety your main concern.
