- the first layer ensures that there is a small amount of radiation from the beam and, as a result, protects the device from being coupled to
- the second layer provides for the maintenance of active components for the active element. Absorption by an active radiation element of the pump causes the effects of this element.
- a beam of laser radiation produced by a known module will have an increased effi ciency. Radiation from a pump in an external laser module is emitted into an active element in the form of a beam of light, a perpendicular primary lamp, and a source of non-hazardous light source. The radiation emitted must be sufficient to be delivered.
- the radiation beams generated by conventional pumping sources are characterized by a significant rapid non-separation of radiation. Therefore, for the purpose of ensuring the separation of radiation from a source of radiation due to the inactivity of emitting emitters, However, such a random light diffusing turns off (dissipates in the opposite direction), and a significant part of the radiation is negligible.
- the width of the active element exceeds its thickness by less than 4 times.

- the module shown in FIG. 4, suppresses the type of disruption of vibrations is ensured due to the loss of user 1 and the receiver is free of charge.
- ⁇ in the form of a plate with a size of 1x5x48 mm 3 .
- the surface of the plate was polished, and the narrow side of the plate was slightly mowed away by the other friend of the friend, as shown in figure 4, for pressure reduction.
- widespread use of the active elements was made in contact with the process of the use of metal smelters from aluminum
- the thickness of these layers was 5–10 ⁇ m.
- the thick layers were able to withstand pump radiation with a density of 2 kKt / cm 2 .
- the pumping was carried out in a pulsed-pulsed mode with a pulse repetition rate of 50 Hz and a pulse duration of 1300 ms. With a pulse output power of around 300, the gain was around 0.4 cm- 1 .
- ⁇ another experimental studied module of the plate of the active element from ⁇ : ⁇ had dimensions of 1x5x12 mm 3 .
- an im- ported method was used for the scheme shown in Figs. 7a, 7b.
- Sources of pumping provided laser diode arrays with integrated cylindrical lenses with a radiating width of 1.2 mm; the active element was obtained by four such sources as shown in FIG. 5.
- the total average capacity of the download was 120 ⁇ .
- Components with internal channels for liquid refrigerant have been made from aluminum alloy.
- the thickness of the interim primary layer was 5-10 microns.
- the current system has a large number of 16 new approach of the amplified beam of radiation along the length of the plate of the active element with a simple shift in the direction of the width of the active element.
- an amplification module was manufactured, which was able to amplify the radiation power of about 20 times and an external power of 2 watts.
- the value of the heat sink through the intermediate optional layer in this module was approximately 40 ⁇ / cm 2 .
