Compact, Lightweight CO2 Lasers for SDIO Applications
Abstract
Two rate equations are important in determining the stability of the discharge. The first is the electron production and loss and the second is the metastable production and loss where ne is the electron density, nm is the metastable density, alpha is the recombination rate, beta is the attachment rate, (sigma v) is the electron impact metastable production rates constant and tau m is the metastable lifetime. The ionization rate constant v in Eq. (1) is assumed to be the result of metastable ionization. Since the metastable levels have a much smaller ionization energy than the ground state the ionization rate of the discharge is dominated by electron impact ionization of the metastables. The stability of Eqs. (1) and (2) will be analyzed assuming that the applied discharge is sinusoidally varying. Hence the various rates are determined by the local RF electric field of frequency w which is generated externally by the system shown in Fig 1. From the analysis performed in Phase I Science Research Laboratory (SRL) has shown that a current source is volumetrically stable and so the initial analysis will assume an RF current source.
