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.

Step 1: 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

Step 2: 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

Step 3: The Key Component

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

Step 4: 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

Step 5: 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
