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.
