PLASMA LASERS
Abstract:
A theoretical investigation of population inversion in C IV recombining
plasmas cooled by adiabatic expansion has been carried out. The non-equilibrium
plasma is simulated on computer using the Collisional-Radiative model which
requires rate coefficients for basic physical plasma processes. We show how
gain per unit length is computed and why large gains occur only in limited
regions of parameter space (ne, Te) we then compare these results with
astronomical evidence. We also show how the rate coefficients and ionization
equilibrium are computed.

- Conclusion.
- It is in the nature of a hypothesis when once a man has conceived it, that
it assimilates everything to itself, as proper nourishment, and from the first
moment of your begetting it, it generally grows stronger by everything you
see, hear or understand.
Laurence Sterne 1713-1768.
