What are we have done??
You may think nothing. But we do something
Optical Tweezer
Optical Tweezers, or traps as they are often called, are created by using a high numerical aperture objective to tightly focus a laser beam, thereby creating a spot where a particle with dimensions on the order of microns will experience a force due to transfer of momentum from the scattering of photons.
This project is demonstrated how laser can move atoms using focus beam and changed 2-μm bead position.

Repumping laser
Hand-made laser by Pongpol Parkprom bachelor student as final project
He actually designed by himself. Such an incredible skill and knowledge.
