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.
