Edit: I removed this video because the info in here isn't helpful and the youtube community has a 99% idiot rate.
Don't want to build one? Buy a 200mW one for $44 here http://www.dealextreme.com/details.dx/sku.11315~r.93098389
***UPDATE***
If you really want to build a laser, please don't use this tutorial. I made this video when I was younger and I didn't know much about lasers. I will have a much better and easier tutorial up in a month or so if you can wait. Until then check out laserpointerforums.com for some great tips/tutorials on building lasers.
If you are going to use this tutorial anyway, the circuit used in this video is a BARE MINIMUM. Although the one I made in this video still works fine to this day, you will probably want to add a small capacitor (anything over 10v 16uf is fine)in parallel with the diode to even out any voltage spikes from the battery. To build a well regulated circuit check out www.laserpointerforums.com for some great, easy to build, current and voltage regulated circuits for lasers.
One thing to note is the prices of the diodes have jumped from $13 to $19.50 but you can buy the diodes off of sales.stonetek.org
If you need more help you can find me and a bunch of other people that can help you on Laser Pointer Forums and Spectraforums!

In this video I show you how to build a homemade high powered burning laser.
Parts:
You can get 100ohm potentiometers off ebay for pretty cheap
You can get you switch and battery holders at any radioshack
You can get your laser diodes at laserpointerforums.com for less than half of the price of pulling them from a DVD burner (and a heck of a lot easier)
You can get AixiZ modules from Ebay Seller aixiz_lasers
A few tips
-DO NOT LET ANYTHING SHORT!
-When you have turned the pot so the brightness turns high, don't even think about turning it more to make it more powerful. If you do that the power will go from 100mW+ to .1mW and your diode will be screwed
-buy more than one diode cause they can break by simply touching them sometimes, too much current to the diode or a ton of other things so you will be safe buying more, and if you have extras build more modules and sell them to your friends for even more fun! (go ahead and charge $100 for them so you can be rich)
-Buy goggles for these things! Goggles cost around $40 and are easily worth it, your eyes are worth more than $40 and if you get hit in the eye by this thing without goggles on, you're screwed.

January 9th, 2009 at 02:28:52 slahbarat...sounds catchy.. lol
January 9th, 2009 at 02:51:51 umm, u made a mistake and wrote tha wrong title for tha song... lol jk just rly bored, merry christmas :)

January 9th, 2009 at 04:23:47 cool my cocackroach friends are going to suffer a lot.
January 9th, 2009 at 04:46:46 god damn your retarded slahbarat
January 9th, 2009 at 05:09:45 worst song
January 9th, 2009 at 05:32:44 Fuck you stupid idiot. That was a long time ago. Just read the whole comments before you post shit. I made a mistake. So what? I have no time for that shit... Btw: Happy new year :D Slah
January 9th, 2009 at 05:55:43 It's "Let the bodys hit the floor" Really.
January 9th, 2009 at 06:18:42 thx for help this is the best help vid
January 9th, 2009 at 06:41:41 no really you are
January 9th, 2009 at 07:04:40 u are so gay
January 9th, 2009 at 07:27:39 Stupid music choice.
January 9th, 2009 at 07:50:38 aaand sry then i tought you came here to just tell him that he didnt spell it correctly my bad
January 9th, 2009 at 08:13:37 All I did was correcting the grammar of Slahbarat since he TRIED to correct someone else, but failed. No need to attack me for that reason.
January 9th, 2009 at 08:36:36 OMG. saltydude answered me that I made a mistake. Sry but this comment you made is really stupid. I don t blame you being stupid. I just say the comment is stupid ^^ Next time read and then write a comment ;-) Buth thx for the Info. Btw: Does anyone else want to tell me that I made a mistake and wrote the wrong title of the song? Yes? Maybe 100 more people want to tell me that ^^
January 9th, 2009 at 08:59:35 No its let the bodies hit the floor, let the party lit the floor doesnt make sense
January 9th, 2009 at 09:22:34 stfu i hate English teachers if we cant spel(2x L maybe?) correctly but who cares if everyone gets point?
January 9th, 2009 at 09:45:33 Pardon me, but "correct English" ain't "correct" at all. It's PROPER English. -David, English teacher.
January 9th, 2009 at 10:08:32 but i dont suposse you dad is in hospital
January 9th, 2009 at 10:31:31 and i say shitmas cuz its a CKY remix of we wish you a merry christmas
January 9th, 2009 at 10:54:30 oh no the total oposite mate too much sex too much beer and pizza no gifts tho its just a waiste of money and time.Chirstmas to me means being with family and freinds
January 9th, 2009 at 11:17:29 In my country we are acting nice to each other. We wish merry christmas even if it was one week ago. MUAHAHAHAAHAH I really have to smile >:-) I found your wound. I ll give you some salt: You say shitmas because your chrismas was really shit. I bet you had no sex no good presents and no friends you have met. I bet that you are only a real-life sucker. Bam. I hope it hurts. I don t like it if somebody insults me without any reasons :-) Slah
