Abstract

An investigation of the optical output for all possible combinations between the capacitances C₁,C₂ in a 'doubling circuit' and in a C-to-C circuit N₂ laser is presented. The results show that, for the doubling circuit, a maximum optical output appears when C₁ equals C₂ for a constant total capacitance. This maximum value increases when the total capacitance increases. This behavior of the optical output is due to the coupling of the two loops which become the best when C₁ equals C₂. For the C-to-C circuit a maximum optical output appears when peaking capacitor obtains a critical value. For low values of the peaking capacitor the optical output follows the rise of the electric pumping pulse. On the other hand, for high values of the peaking capacitor than the critical one, a part of the electric energy arrives at the laser channel after the laser output, while the exploitable electric energy decreases causing reduction of the optical output.
