How to make a powerful burning laser for CHEAP!

After watching many videos on youtube of people burning things with high power lasers, I wanted one.Those lasers can cost a lot of money though, something I don't have. So I made one, and in this instructable, I will show you how to make one for less than ten bucks. This is my first instructable, so if I did something wrong, please tell me. This laser outputs between 50-100 milliwatts(I think), and can burn electrical tape, light matches and melt thin plastic.I was messing around with this laser one day, and I shined it at a mirror,  and the laser shined back in my eye for a second. I heard a popping sound and I couldn't see anything for a couple of minutes. Now, I was LUCKY that I did not get permanently blinded, but if I shined it a second longer I probably would have been. Now with that said, NEVER point a laser at another person, animals, or any other living thing.

Okay, Now lets make the laser.

You will need:

1. A old DVD drive (free)

2. A LM317 ($2.00)

3. 10 ohm resistor ($0.10)

4. An Aixiz Module from here: ($5.00)

5. 6-volt battery pack from Radioshack ($1.99) 


Tools Needed:

A soldering iron (free)

Screwdriver (free)

Total Cost : $9.10

Step 2: Get the diode

Remove all the screws on your DVD drive, take off the rails by removing the screws that hold it in place and take off the laser tray. There should be two diodes on the laser sled, one of them is infrared. You can test for the red diode by hooking the diode up to a 3 volt battery pack. Then remove the weak 5 mw laser module from the Aixiz housing and add the new laser diode from the DVD laser assembly. Solder 2 wires to the positive and negative of the laser diode according to the diagram.

What is the use of Aixiz Module? And can I make it without Aixiz Module?

Will a LM 1738 work??? Also I cannot find the diode. On the laser tray(that slides about) there is something I managed to pull out somehow but how to check whether or not its a laser??? Also from where I can give it power??? Please help!!!

im making this for a school project. do you have any tips or tricks on how i could make it stronger, diffrent colored, etc...?

Serves a 200 mw laser diode

This sounds like a stupid questtion but what color will the laser be?

Normal lasers are red. BlueRay are....blue and super high powered ones are usally green

Hello i took parts from a old radio cd player

10 ohm resistance ( i have been lucky only 1 in it lol )

and transistor ( not lm317 ) but 2SD882

A laser diode from a ps3 bluray kem-450 DAA , 3 pins .

All seem to work with a 6V battery but i need at least to buy the module .to focus the light .

Because for the moment it look like a flashlight not a laser .... ( blue light )

brightness is very low, I have made a mistake? or should i buy a module then try again ?


Thanks :

Hey, do you think a diode from a Blu-Ray player would work for this?
Thanks

why would you destroy a blu-ray player!?

joeismydad (author)  aklreaxmer3 months ago
I'm sure it would work, I just don't know how much power (mw) your Blu-ray diode can put out, and the driver in this instructable may not be suited for your diode. Also, the color of the laser beam would be blue instead of red.

Hi I remove the laser sled and I see one diode. On your picture the diode is encased. Do I need to remove everything around the diode? Where is the positive and negative on the diode? Thank you for your help.

i connected the laser diode directly to 3v power it worked properly 4 1 day !! but de next day it is nt glowin properly! n itz nt burnin anything!! wat is de use of de transistor ??? hw can de laser b burnin?? replz plz
joeismydad (author)  blindrulz3 months ago
Sorry for the late reply. Your laser is not working now because you connected the diode directly to the battery without using a regulator or driver. You're actually very lucky that your diode lasted a day, most diodes will fry in about 20 seconds without a driver. The transistor (LM317) is an adjustable voltage regulator; the voltage can vary between 1.25 to 37v, depending on what you set it to.
Hello, I wanted to ask you coisa.Ao replace the diode aixiz weak, will still use the circuit before you changed it?
joeismydad (author)  guilhermee_1233 months ago
No, do not use the driver/circuit that came with the module. That driver is used to power the weak 5 mw diode, and will not give optimal results (if any) when used with the new diode.
When the diode pain replaced by another circuit before modification, ie, the original is needed or the drive is making the necessary

Hey, I've been working with lasers for a While now, Love them sooooo much. but anyways to the point. You can get a 20X laser diode for 9 dollars at a place called Modwerx.com, and use a 3 Ohm resistor and you can get about 200-250mW's, you can use a 5 ohm resistor with yours too. and get a good 150-160mW's!
hope this helps!
Thank you for your reply. Could you burn polythelene plastic 3mm with white or opaque colour??

is there anywhere i can get one of those modules besides the internet
Not really. Cheapest is on ebay. Normally about $8. $5 plus $3 shipping.
Here's a link to great modules that have copper to act a a great heatsink.
3 for $16, so $5.33 each. And they are super fast shipping located in the USA,

what ohm resistor would i use if i used a 9 volt battery instead of a 6 volt battery?
This is a proper driver circuit for a red burning laser. You can use a 9 volt battery with it.

Use a 50ohm 20-turn pot, not a fixed resistor. Set it at minimum current (max ohms) Then put your laser in the place of the LED. No lens. You want it to be pointing at a white wall, lighting up the whole wall. Turn up the current very slowly. You'll notice interference patterns on the wall. When your laser reaches its MAX current, the patterns will suddenly shift. QUICKLY back the current off a bit, and you are now at the max safe operating current for the laser. AKA, as bright as possible without burning it out. Don't forget to heat-sink BEFORE you start.
Also, be very careful turning it up, and QUICK about backing it off or you will destroy the laser. The sudden shift in the pattern is it's way of telling you it is getting too hot!

i have 4 wires on my diode
ThatCatMan10 months ago
Well I found the laser diode, but it's hard mounted onto the laser sled and housing. What should I do?
im going try the diode from an original xbox dvd and games disc player it already worked when i added the plain 3 volts so i hope it works with the burning circuit.

how to extract laser from cd writer can u tell me
gauravclb9610 months ago
will increasing the power of class 2a laser would work burning things as my laser pointer is working on nearly 3 v if i would make a laser driver circuit and use laser pointer diode which is class 2a as written on it will it burn things
xyle66610 months ago
was wondering instead of using the lm317 if i could use a lm2596? i have a bunch of these around since i build variable voltage e-cigs. yes its 3watt output instead of 1, but not sure what kind of difference that would make.
hi, how can I tell which way to put the resistor round, ie which end goes where.
Resistor is non polari...... Oh, sugar, I just realized ur bein' sarcastic. My bad!
no i wasnt being sarcastic, I really didnt know, but I do now. thank you all for any help. ok the place i bought it from says its only a 10mw diode, which could be the reason it wont burn anything. I am in contact with him to find out how much he might charge for what actually need.
Sorry reever. Any how resistors don't have polarity, either way round is exactly the same. Also, 10mW can burn some stuff, and if you raise the supply voltage on laser diodes you increase the output, but you trade off longevity, plus you increase the risk of thermal failure (breakdown through overheating>

now, just wait for your neighbor to set a matchbook on the counter... >:D
Sorry dudes.........but
De thought police is here with de offishal SAFETY WARNING:
DO NOT OPEN AIR THIS THING.
The design daddy's boy posts doesn't use enough current to really pour sugar on everything, but it is a Class III device.
THERE ARE FEDERAL LAWS ABOUT THIS THING!!
Just a few more mA, and Joe is my dad would have been been permanently BLIND, LONG BEFORE HE COULD BLINK!!

Now, Having Said that: I'm a Gonna keep my neigbours coffee warm, while it sits on his desk, all in line with my You have poltergeists not living at your house running gag. ( I wonder why he seems to be so nervous these days?,I hope it's only because he figured out my Instructables account password).
Kevin? are you there, Kevin??

My doctor say that the laser burnt a hole in my retina. I have a permanent black spot in my vision:(.
Sorry ' bout the hole in your eye. Dude, please use laser goggles next time and never let the beam fall on anything that reflects. Every time you plan on using a laser, always Know the path the beam is going to take and use a rough, black non reflective backstop to ensure the beam doesn't finish your job and go next door, and do the neighbor's dog.

And yeah, I really like the "you have poltergeists not living at your house" gag. So far I've made ghosts speak to him from his garbage can, and I used a photo detector and a pulsed radio transmitter to make his doorbell ring 25 seconds after he closes his bathroom door, ( at random times, of course, the gag fails if the bell rings every time), and I've made his front gate opener cycle back and forth during the opening cycle if he tries to open his gate before 7.00am on sundays (he goes to the local farmer's market then.
All my gags are fun, they're not to hurt, inconvenience or seriously irritate anybody.... So, if you can think up of some subtle, non-hurtful gags, that mystify without harm, let me know, and I'll try to engineer them.

Hve fun with your lasers though.

I haven't really pranked my neighbors lately, I don't want them to hate me... As for prank ideas, I can think of some gags I have pulled on my nieghbors before like lighting a pot full of fireworks WITH A LONG FUSE, then ring the doorbell and run >:) , and I have added a couple bottles of food coloring to their fountain so all the water turns blue...
The pranking is mutual, and we don't do things to cause discomfort or (shudder!) extra work. We just try to mystify each other. Success is defined as 1: it takes a while to realize that its a con, and it takes longer to figure it out.
Cool?
