MnBr vapor active medium with a built-in reactor at 100-kHz pulse repetition frequency

Frequency and energy characteristics of a MnBr vapor laser with a built-in reactor, i.e., with gas vapors being produced within a gas discharge tube, and the dependence of the average output power on different parameters are studied in this work. The values of the GDT wall temperature and buffer gas pressure required for obtaining the maximum output power are determined. It is shown that active media of this kind are as good as media with a conventional method of gas vapor production. A pulse repetition frequency of 100 kHz is attained for the first time for a medium on Mn atom transitions. The use of this active medium as a brightness amplifier in active optical systems is described; the amplifying characteristics are analyzed.

Frequency-energy and amplification characteristics of the CuCl laser with an internal reactor

A new method for the creation of vapor of a working substance in lasers on atomic transitions is presented. The frequency-energy and amplification characteristics of the CuCl laser that is excited by a barrier discharge are studied. Such a method for the excitation allows an increase in the working lifetime of the active element, since the internal electrodes are rapidly destroyed in chlorine atmosphere. The experimental dependences show that such an approach makes it possible to construct lasers with output parameters that are no worse than the parameters of conventional lasers on metal halides and the amplification characteristics are similar to those of the known active elements.

Study of scalability of capacitive excited CuBr lasers

In this work, we study experimentally the output performance of a middle-scale CuBr laser with longitudinal capacitive discharge excitation. Lasing power dependencies on different operating parameters are studied, including the equivalent electrode capacitance value. An average output power of 12 W, the maximum to date, has been attained in the CuBr laser excited by a longitudinal capacitive discharge with ∼0.5% efficiency. This result has been obtained with a total calculated electrode capacitance of 1190 pF on the each side of the gas discharge active region.

Blue-green laser radiation from dyes in matrix

Lasing properties of two dyes in polymeric matrix radiating in blue-green region of the spectrum pumped by a XeCl laser are studied. The lasing efficiency and photostability of the solid state active media are compared with corresponding characteristics of the same liquid active media.

Iron bromide vapor laser

We have studied the characteristics of a pulsed gas-discharge laser on iron bromide vapor generating radiation with a wavelength of 452.9 nm at a pulse repetition frequency (PRF) of 5–30 kHz. The maximum output power amounted to 10 mW at a PRF within 5–15 kHz for a voltage of 20–25 kV applied to electrodes of the discharge tube. Addition of HBr to the medium produced leveling of the radial profile of emission. Initial weak lasing at a wavelength of 868.9 nm was observed for the first time, which ceased with buildup of the main 452.9-nm line.
