WebPassing a single laser beam through a vapor cell of a two-level gas results in basic laser absorption spectroscopy. This affects the number of atoms in the ground state and excited state, but the random thermal motion of absorbing atoms causes Doppler broadening. The horizontal velocity parallel to direction of laser propagation, v z, of these Webstabilize the laser frequency to a specific atomic transition. Various spectroscopic techniques such as saturated absorption spectroscopy[2-4], polarization spectroscopy[5], dichroic-atomic-vapor laser lock (DAVLL)[6, 7], and selective reflection spectroscopy[8-11] have been used for sub-Doppler or Doppler spectroscopy in alkali vapor cells.
