SUMMARY
The discussion centers on the concept of "eV per Torr*cm," specifically in relation to nitrogen gas and its application in laser technology. This unit represents an ionization constant that connects electric field strength to the energy required for ionization, as outlined by Paschen’s Law. The energy per collision is influenced by the mean free path length, which is inversely proportional to pressure. The constant is crucial for determining the energy necessary to excite the lasing state, rather than merely the minimum energy for discharge.
