Topics
- Laser
- Photon Beams
- Quantum Mechanics
Description
Create a laser by pumping the chamber with a photon beam. Manage the energy states of the laser's atoms to control its output.
Sample Learning Goals
- Describe how absorption and spontaneous and stimulated emission work, and explain the requirements for each to occur.
- Describe how a laser works.
- Explain the requirements for lasing in terms of the intensity and wavelength of the lamp, the mirror reflectivity, and the lifetimes of the excited states of the atom.
- Troubleshoot a broken laser.
