Introduction: How to Make a Laser
After opposition against this instruction by some of the members i realized that there are some problems with my attempt to make laser. In this instruction i do y best to portrait how a laser works and how to make one.
This is an expensive project.
Step 1: What Is Laser
If you want to make something first you should know how it works.
So what is a LASER?
LASER is an acronym for LIGHT AMPLIFICATION BY STIMULATE EMISSION OF RADIATION.
Step 2: The Structure of a Laser
A laser works this way :
Imagine a pipe with a rod of ruby and an illumination inside it and a coil around the pipe.
This is the structure of a RUBY LASER a easy-to-understand laser because there are many types of lasers.
Step 3: How to Make a Laser
At first this instruction was about how to make a laser which appeared as a vain attempt because i forgot about the ruby part but i try to fix it as soon as I can.
Here are the requirements for this project:
3-pipe: I used a plastic pipe my self and I don't know if using iron metal pipe will do or not.
4-wire for making coil
7-ruby rod that fit's in your pipe tightly
Remember that you ruby bar should be shorter in length than your pipe.
Step 4: Making the Coil
All right burn one end of your wire and remove the blackened part because we want to connect it to a power source.
Wrap the wire around the pipe I myself wrapped it three times.
After finished with wrapping you should cut the wire in a way that it has enough to get connected to a power source.
Burn the other end of the wire and remove the blackened part.
After you wrapped the coil tape the end of it.
Step 5: Assembe Your Laser
Solder three LEDs in parallel on a PCB board and glue it to one end of the pipe and connect the wire from the coil to wires coming from LEDs.
Now put the ruby rod inside the pipe.
Step 6: Finish
The longer the length of your pipe the length of your coil and the more voltage you gonna need. The pipe I used myself was about five centimeters and took 9 volts to operate.
We have a be nice policy.
Please be positive and constructive.
