Homemade laser
For this experiment we created a laser pointer.
The scientific Method
Question: How do lasers work?
Materials: 2 Plastic Candy Tubes, Red laser Diode, 2 AA Batteries, Tin foil, and Hack saw
Experiment steps:
1. Gather all Materials
2. Took the laser out the box
3. Hacksaw plastic containers so batteries can fit
4. Extracted a metal spring from a remote so we can create a circuit
5. Put the batteries inside the tube.
6. Find out what part of the tube the battery reaches and use the hacksaw to cut under the battery so we can connect the wires to the positive and negative.
7. Use electrical tape to keep the laser diode in place.
Experience:
For this experiment we had to play around and figure how to do make the laser pointer our own way because we didn’t have the same materials as most of the videos we have seen. The length and widths were different and the length was the only thing we can change. We can change it by cutting it with a hacksaw. Griffin tried using one AA battery to see if the diode worked and we started worrying because the diode didn’t respond. After that I proposed to try it with 2 battery and it worked. The lack of energy turned out to be the problem. As we went inside the classroom to drop off the hacksaw I spotted a control from the dvd and got a idea to make the controller into a laser pointer instead. We took the remote and dismantle it so we could use some of the parts. We used the spring from the remote to create a complete the circuit. In order to place the spring inside the plastic tube we used the hacksaw to cut open the tube and made sure the battery was touching. We then grabbed the laser diode and tape a wire of the diode to the spring. To complete the circuit we used the other wire and taped a tin foil to the end so we can just add pressure to the negative side of the battery.
Science Behind It:
A laser is a special form of light. Laser stands for Light Amplification by Stimulated Emission of Radiation. A laser has a laser cavity mirror that has two mirror and in between photons. Those photons need to get excited or energized. After the photons have been energized the photons will hit each other and amplify. As the photons are bouncing off the two mirrors one of the mirrors is designed to let 1% of the light come through. Since all the photons are traveling in the same path the laser will be linear.
