MW peak-power UV inductive nitrogen laser

Pulsed inductive CO2 laser with radio-frequency excitation and influence of the H2 content on the efficiency and lasing temporal characteristics

“…Another difference of the inductive nitrogen laser is the maximum output energy achieved at relatively low pressures-up to 5-6 torr. At the same time, the output energy reaches a value of 11 mJ with a pulse power above 1 MW [13], which is quite comparable with the values of the best electric discharge nitrogen lasers, whose characteristics provided by the working gas medium pressure are at the level of at least tens of torrs. In addition, for pulsed inductive nitrogen lasers, the possibility of changing the lasing duration within a fairly wide range (10-20 ns) was demonstrated, and this was demonstrated for one laser system design (by changing the Q-factor of the resonator).…”

“…For comparison, the same figure shows the oscillograms of the voltages across the capacitors C 3 and C 4 of the discharge circuit and the lasing pulse of the UV nitrogen laser, for which, instead of the Ne-H 2 mixture, nitrogen was added into the discharge tube. The beginning of the UV lasing pulse corresponds to the maximum current gradient through the inductor dI/dt, that corresponds to the maximum inductive ElectroMotive Force (EMF) in the active medium [23]. In this case, the pulse of neon lasing is located approximately 30 ns away from the lasing pulse of the UV nitrogen laser, and is formed when the inductive discharge has actually extinguished.…”

“…To carry out the research, we used a system for pumping by a pulsed inductive cylindrical discharge (figure 2), which does not differ in its main characteristics from the scheme described in [23]. A feature of this scheme is the possibility of realizing a high specific pump power, that allow, for example, obtaining UV lasing with a megawatt pulse power in nitrogen.…”
