“…Thus, as suggested the gas discharge in the active medium occurs without the electrical breakdown and the equivalent circuit is the simple oscillatory circuit [3]. However, this equivalent circuit cannot explain the observed experimental dependencies, particularly the realizing of the efficient pumping of the active medium of the LSTM operating in the energy input cut-off mode [5,6].…”

“…The highest value of the efficiency of the pumping of ~ 9 % of copper vapor laser operating in the energy input cut-off mode (the energy input into the active medium was excluded after a laser pulse) was achieved [5,6]. It can be explained by the fact that sharp-front pulses, which duration is equal to the lifetime of the population inversion of the operating levels in the active medium [1], should pump the LSTM.…”

“…In the experimental researches [5,6] the managed switch consisting of the thyratron TGI1-270/12 and the tacitron TGU1-27/7 was used, what helped to realize the energy input cut-off mode at the circuit current of 27 A. According to the experimental researches [5,6], the circuit current at the end of a laser pulse was higher than the mentioned value.…”

“…According to the experimental researches [5,6], the circuit current at the end of a laser pulse was higher than the mentioned value. Therefore, the tacitron should be close before the end of a laser pulse to realize the energy input cut-off mode.…”

“…It is obvious that the modulation lamps GMI-29 [3] is the ideal switches for the lasers operating in the energy input cut-off mode. However, the efficiency of the pumping of the active medium of the LSTM with the modulation lamps that is equal to the value from [5,6] was not realized. Thus, there are the several unanswered questions that limit using the energy input cut-off mode for the creating of the efficient sources of coherent light.…”

Abstract. The analysis of the electro-physical processes in the discharge circuit of the lasers based on the self-terminating transitions of metal atoms (LSTM) and the electrodes placed in the cold buffer zones of the gas discharge tube (GDT) is occurred. That design of the GDT can provide the efficient lasing at the reduction of the current flowing through the switch to zero after the charging of the capacitive components of the circuit from the storage capacitor. Under the circumstances the pumping of the active medium is determined by the energy input from the peaking capacitor and, consequently, the efficiency of the pumping can be increased by an order of magnitude, if (using a managed switch) the energy input into the active medium from the storage capacitor is "cut-off" after charging the capacitive components of the circuit. It was shown that the efficiency values of ~ 9-11 % and of ~ 5-6 % for the copper and gold vapor, lasers could be achieved.

UDC 621.373.535The effect of the design features of the gas-discharge tube on the processes proceeding in the discharge circuit of a metal-vapor laser has been investigated. The position of electrodes in the gas-discharge tube has been found to significantly affect the processes at work in the discharge circuit and the energy characteristics of the laser. For instance, gas-discharge tubes with electrodes placed in the hot region of the discharge channel are typified by high metastable-population rates at the leading edge of the excitation pulse, whereas with electrodes positioned in cold buffer regions, the leading edge of the voltage pulse across the resistive component of the tube impedance is seen to peak. Conditions for running-wave generation in the active media of lasers on self-terminated transitions of metal atoms and the running-wave use efficiency for laser pumping are discussed, considering a strontium-vapor laser as an illustration. It is shown that the running wave is generated as the result of the breakdown in the anode end of the gas-discharge tube and is maintained by the energy stored in the capacitive component of the impedance of the gas-discharge tube. The lasing pulse duration under running-wave excitation corresponds to the time it takes an ionization wave to propagate from the anode to the cathode of the gas-discharge tube, with pumping efficiency being ~6-8% for a strontium-vapor laser. The average lasing power varies within 10-15% depending on whether the totally reflecting cavity mirror is placed near the anode or the cathode of the tube.
