I did a search on here and I couldn't find anything about this.

How powerfull is the output of a typical laser Diode in a laser printer have?

Thanks

Power will vary dependant on type of machine I do know that most are of IR so........ if that helps ;)

I don't think it is going to be very powerful. The laser doesn't actually burn anything. It creates a positive or negative charge on a film in the shape of whatever you are printing, then the toner sticks to that charged film, then the film rolls over the paper, then the paper goes through a heating element that burns the toner to the paper. but having said that, i still don't really know what power level it is capable of.

The biggest reason of why I asked this question is because when I was like 18 years old and I didn't know anything about lasers, my uncle told me that he took one out of a laser printer and it could burn holes into walls.

Now that I am 23 and have made a few lasers, I don't believe him for a second and I would like to prove him wrong. When I showed him one of the lasers that I have made, he started telling me the story all over again. This was a month ago. I asked him where it was and told him that I wanted to see it. He told me that it stoped running and him and his buddy threw it away.

Leave him with his fantasy . . . . . it's all some people have . . . . . You know. That's all that really matters

It's easier to be kind

Peace,

I know, but he is always one of those people that has to 1 up you.  (Always has something better or cooler)
It would like to win for once!! ;D

the only way i would know how to make a hole in the wall with a laser printer laser diode would be to leave it in the printer and throw the whole thing directly at the wall. That should teach him. :D


thanks

From Sam's Laser FAQ

http://repairfaq.ece.drexel.edu/sam/laserdio.htm#diolpv1a

Laser diode and optics characteristics:
Type: Sharp LT020MD (index guided).
Wavelength: 780 nm.
Maximum power: 20 mW with TE cooling, 5 to 7 mW typical without (as in this unit).
Lasing threshold: 60 to 70 mA typical.
Electrical configuration: Case is common negative.

Collimation optics: Mini-optic rail with a C/CX or 3 element collimator, and an f theta lens. These optics (except the 3 element type) work with laser diodes up to 150 mW and 635 nm wavelength. The 3 element type works with 670 to 1300 nm laser diodes as well.
Note that this is only the front-end. It does not include the beam scanner (motor driven multifaceted mirror), field correction and directing optics, or beam position sensor - which would be present in a complete laser printer. The output of this module is a collimated IR laser beam. The actual focal point will be at the image plane (photosensitive drum surface) after passing through the other optics.

NOTE:
Some older, first generation, laser printers had actual helium Neon lasers, before solid state diode's became easily available.

He did say that the Laser was rather large.

He has to "one up" you because he is frightened (or knows) that you are better than him and it scares him. Don't get caught in the same trap.

You know. That is enough. Leave him be. [/dad]
