The optimization of power absorbed by nitrogen laser circuit were developed and scalingrnparameters are identi ed with MatLab algorithm so as to enable a study of the laser overrnits range of discharge modes. Results are presented for the critically damped laser gaprnand for the more typical case of damping factor 0.4. The analysis shows in a typicalrnnitrogen laser the rate of rise of the laser gap voltage dVg=dt prior to laser gap breakdownrnis 0.5kv/ns and such a (dVg=dt) is required for a uniform breakdown across the laser gaprnfor a good lasing action. The power absorbed by the channel is 70% when the laser gaprncircuit is critically danped. For the case of damping factor 0.4 the power absorbed isrn65%. Thus it may be concluded that in the present work optimum power absorbed byrnthe channel is 70%
