Diy Laser Burner Module From Old DvD'wr.

This tutorial is about how i make my own laser diode from old dvd writer. I need such a laser burner module for my cnc engraver project such type of modules are very expensive on many websites. so i decided to make my own.

Lets Assemble Lens

First insert the plano convex lens from an old laser pointer in to the aluminium tube in my case both fit well
than place the paper spacer to insert the another lens (spacer ring having width of 7 mm and length of 3 round)
then put the another convex lens to the spacer ring

The Component

components I needed is a dvd driver in my case it is samsung
and a heat sink from a old motherboard
a old laser pointer (lens)
a super glue

The Key Component

The key component of this project is this laser diode from old dvd writer lens module

Putting All to Gether

Now glue the laser diode on the heat sink as you can see in the first image
now apply the glue and then glue the lens tube now its done
i also soldered three wires to the diode

Lets Test It Out

now power it up with with 3.3v @400mA
there are two laser diodes in in one for burning and on for reading we only need to power up the burner
wear some safety goggles to protect your eyes.
and it is quite powerful
