Gain and Loss are the fundamental factors contributing to laser effectiveness. Simply put, the gain is the light produced by stimulated emission and loss is then the light lost.
This can happen if a photon hits an electron in a low energy level state and the electron absorbs the energy and moves to a higher energy level state. It can also happen when light escapes the
laser cavity. Lasing is the condition when the gain exceeds the loss. It is very important to know the gain to see how effective your laser really is. The traditional Hakki-Paoli Method was found
to be ineffective for measuring gain in quantum cascade lasers. A new, more effective method of measuring gain in quantum cascade lasers was developed and tested.
