“…The plot shows an example of maintaining a specified pressure for an hour. However, it should be noted that the laser in [6] operated for 1500 h without deterioration of the characteristics. In this case, the procedure of switch ing the laser off and on (attaining the operating mode) using the RS was multiply performed.…”

The design and operation of a reversible zeolite based HBr source for a copper bromide vapor laser are described. Porous zeolite absorbs or liberates gaseous HBr depending on the temperature, thus allowing efficient control of the HBr component pressure in the laser active medium. The temperature dependences of the admixture in the initially evacuated working volume and at pressures of the Ne buffer gas of 30 and 60 Torr are presented. The reversible operation of the device in dynamics is shown.

“…This is much more convenient when operating with metal vapor lasers. The use of the RS of HBr made it possible to develop an efficient CBVL [6]. Studies of the influence of the admixture dose on the laser characteristics in [7,8] point to the expedience of controlling its value.…”

“…3]. We used a copper bromide vapor laser as a source of radiation [2]; it was constructed at the Institute of Atmospheric Optics, Siberian Branch, Russian Academy of Sciences, and has the following characteristics: the radiation wave length λ = 510.6 nm, pulse repetition rate f = 11 kHz, pulse duration Δt = 30 ns, power P = 4-10 W, beam diameter at the entrance to the atmosphere ∅ = 15 mm; and radiation divergence Δν = 0.06 mrad.…”

Results of field experiments on the influence of atmospheric conditions and some instrumental characteristics on the quality of information transfer in a bistatic optoelectronic communication system (OECS) operating in the visible wavelengths range are considered. The length of the atmospheric channel reached 17 km. Radiation of a copper bromide vapor laser with a wavelength of 510.6 nm was used as a signal source. It is shown that bistatic or over the horizon OECSs can operate both under the conditions of a cloudy and cloud free atmosphere. Average values and standard deviations of communication errors were estimated under different atmospheric optical conditions when some characteristics of individual instrumentation units varied. Keywords: bistatic optoelectronic communication systems, field experiments, optical and meteorological state of the atmosphere

“…Thyratrons TGI1-270/12 provide the maximal PRF of 50 kHz [26], but TGI1-1000/25 are used widely because of more high switching voltage and stable operating mode [27,28]. Tasitron is another type of gas discharge commutators and its operating frequency exceeds 100 kHz [29,30].…”

The paper is devoted to research the single-pass operating mode of active element on copper bromide vapors and time dependence of ratio «signal/ASE». The results show how the single-pass radiation power depends on time delay between ASE pulse and moment when the input signal enters to active element. Light waveforms (ASE, input signal, output signal) are recorded at each time delay. The minimal time delay was 5.2 ns, power radiation in this case was 3.47 W. The radiation power was reducing as the time delay was increased in increments of about 2 ns. The waveforms prove that the active element output signal contains two components: the first – ASE (amplified spontaneous emission), which is formed as result of the active substance atom excitation and their further spontaneous transitions; the second – single-pass radiation amplified by means of inverse population of the active media. The waveforms allow to estimate the useful signal to noise ratio or other words «signal/ASE». The highest gain is provided with the lowest time delay due to the population inversion is maximum in this case.
