Experimental and theoretical investigation of a traveling wave excited TEA nitrogen laser

Nitrogen lasers, optical devices of variable gain coefficient: Theoretical considerations

“…Spark Gap Oscillator given by R 2 ¼ R g þ Z 0 , where R g is the resistance of the laser discharge and Z 0 is the characteristic impedance of the transmission line [3,8]. For a uniform electric field, E, between the AMP electrodes, R g is given by…”

“…The interest arises due to the fact that N 2 -laser can be easily made, and is a useful optical device in any optical research laboratory. From the theoretical point of view, although many papers have been published on the subject [1][2][3][4][5][6][7][8][9][10], there are many questions that have not been properly answered up to the present years. For example, when the rate equations are used to calculate the output characteristics of the laser, there is an ambiguity for selecting appropriate electron impact-excitation cross-sections from the ground to the upper, C 3 P u , and lower B 3 P g electronic energy levels.…”

Spark Gap Pressure and Lasing Behaviour of a non -Blumlein type Nitrogen Laser

“…It has already been discussed in [1] that the rise time of the firing switch in a normal pressure nitrogen laser must be very short in order to yield high population inversions within the life time of the upper C 3n u state of around 2.5 ns [3,4]. Also, the rise time of the spark gap must be short compared to the time necessary to build up the electric breakdown of the nitrogen in the laser channel.…”

Gain and saturation energy characteristics in transversely excited N2 lasers

“…In N 2 lasers, the electron temperature is related to the E / p value, given by, 10,11 kT e ͑eV͒ = 0.11͑E/p͒ 0.8 , ͑1͒…”
