Question: What do you plan to do with the the lasers in a more detailed level?

Joe Spencer answered on 13 Mar 2015:

So I use lasers to measure vibrations in a material.
If you were to flick a piece of wood or glass they’d sound different, this is because the way vibrations move through the material.
I can use a laser to excite (flick) materials and then some energy is transferred to causing a vibration, when i look at the light that hasn’t been transferred to the material, the difference between that and the one i added in is equal to the vibrational energy.
Studying these vibrations is called Raman Spectroscopy, and tells me alot about physical properties of materials, as well as electronic properties (like how good it is at conducting electricity) which is useful to know if i ever want to make electronic components that go into your phones and computers out of these materials.

Hope that helps
