How to build a High Powered
Burning Violet Laser
This tutorial shows you how to
build a 80mW-100mW violet laser module for about $30 from easily
obtainable parts.
Parts List
A
PHR-803T Sled A 100mA
Driver (The seller no longer sells plain 100mA drivers so you will
have to buy an adjustable driver and set the current
yourself. Instructions for doing this are on that site.) An
Aixiz Module
Tools
Vise
Soldering Iron
Part 1 - Extraction
Start by pulling the Metal Protector off of the sled.
From there you'll see two laser diodes exposed, the one with three
pins is the violet laser diode, the one with four pins is a weak Red/Ir
combined diode. Practice extracting on the red/IR, if you mess up one
the red/IR one it won't matter because that diode is useless for our
purposes.
Next pull out the laser diode in its mini heatsink, you may have to
put a little force into breaking it off from the rest of the sled. Be
careful not to touch the diode during extracting because the glass
window on the front can break easily
After that pull the diode in its mini heatsink out by grabbing the
little ribbon cable and pulling on it.
To get the diode out of its little heatsink, grab both sides of the
heatsink with two pairs of pliers and twist in opposite directions,
this will crack the heatsink metal and the diode should fall out. If
it doesn't just drop out, clip at the heatsink with some diagonal
cutters (or something like them) until the diode falls out.
Now that you have your diode exposed, treat it with care because it is
very fragile, the glass window on the front of the laser diode
shatters easily.
Part 2 - Pressing the
Module
Now drop the laser diode in the top half of the Aixiz module, put the
back half of the module over the diode pins so the diode pins fit
through the small hole in the back of the module.
Put this diode/module "sandwich" in a vice, try to
keep the laser diode as aligned straight with the Aixiz module as much
as possible.
Tighten the vice until the laser diode is flush with the Aixiz module
(the little PCB on the back won't be flush, it will stick out a little
which is fine)
Part 3 - Soldering
Everything Together
Now put the top half of the Aixiz module in the vice
Now turn on your soldering gun and put a blob of solder on the tip of
the gun
Drop the blob of solder on the diode pins and use you needle nose
pliers to pull the PCB off while the solder is melted. Don't keep the
soldering gun on the laser diode pins for more than a few seconds
because your laser diode will die if it is heated too much.
For what you are going to do next, you will need to use this pin-out
diagram.
To make things easier, you can just break off the "Not
Used" pin of the laser diode
Now solder the "+LD" of the driver to the positive
pin on the Laser Diode, and solder the "-GD" of the
driver to the negative pin of the laser diode.
Now screw on the back half of the Aixiz module
Put the spring and lens back in the module
Grab a power supply that puts out 7.25v-12v, a 9v battery works
perfect for this. Hook it up to the laser module and you are ready for
some playing around!
Matches should light with ease!
