You might plan to have somebody inhale the polarized gas, then look at the insides of their lungs,Laser pumping - Wikipedia,Laser pumping is the act of energy transfer from an external source into the gain medium of a laser. The energy is absorbed in the medium, producing excited states in its atoms. When the number of particles in one excited state exceeds the number of particles in the ground state or a less-excited state, population inversion is achieved.Optical pumping - Wikipedia,Optical pumping is a process in which light is used to raise (or "pump") electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction, to pump the active laser medium so as to achieve population inversion.

Optical pumping studies of vibrational energy transfer in,

To summarize, optical pumping in air can be thought of as occurring in two steps. Step one is the direct laser excita-tion of CO vibrational levels 1 to ;9 by absorption of con-tinuous wave CO laser radiation. Step two, which consists of both inter- and intraspecies collisional V–V transfer, thenFrequency-dependent optical pumping in atomic Lambda ,Frequency-dependent optical pumping in atomic L-systems J.
