Experimental results and calculated data on the study of the temperature dependence of the lasing efficiency of the pulsed three-micrometer YAG:Er3+ laser in the range T = ?80 ? +80°C are presented. It was shown that a decrease in the laser crystal temperature from room temperature to T = ?80°C leads to an increase in the laser output energy by a factor of 3?4 at the same energy of lamp pumping. Accordingly, the differential lasing efficiency increases (about three times). 相似文献

For controlling the linear power density in the reactor core, the Khortitsa-M software program as a part of the in-core instrumentation system (ICIS) employs only self-powered neutron detector (SPND) data with the neutronic calculation for the consistent determination of the power density in unmeasurable fuel assemblies (FAs). The confidence of the interpretation of the SPND data essentially determines the safe and efficient operation of a reactor. Previously, it was assumed that the gamma-ray fraction in the reactor radiation does not exceed one percent and is independent of the fuel enrichment and the FA and SPND burnups. Since it is difficult to estimate the contribution of the reactor gamma radiation to the SPND current experimentally, in this work, we present a calculated estimate using modern software and libraries of constants. On the basis of the results of this study, the question is discussed whether it is appropriate to take into account the reactor gamma radiation in the transfer function from the SPND current to the power density of six fuel elements surrounding the SPND with allowance for both the type of FA and the FA and SPND burnups. 相似文献

The characteristics of individual pixels in Si Pt: Si matrices were studied by the surface electron-beam induced voltage method.
The potential of this method for the nondestructive testing of large-scale (several micrometers in size) recombination-active
defects in the working regions of matrix elements was demonstrated. 相似文献

Experimental results and calculation data for the thermal conditions of the YAG:Er laser active element shaped as a flat plate under pumping by continuous radiation of a diode array (λ = 980 nm) with fiber output are presented. The thermal field and temperature in the plate optical excitation channel are measured using the thermal imaging technique. Their dependence on the pump power is studied. A comparison of calculated and experimental data allowed the determination of the heat transfer coefficient from the YAG:Er crystal to air under conditions of natural convection. 相似文献

Zn–Se crystals are used to analyze prospects for application of two-photon confocal microscopy in the study of plane and volume interband and impurity luminescence in semiconductors. Such maps can be formed with a depth step and planar spatial resolution of several micrometers at distances of up to 1 mm from the surface. The method is used to detect luminescence-active inhomogeneities in crystals and study their structure and luminescence characteristics. Prospects for the application of the two-photon confocal microscopy in the study of direct-band-semiconductors and materials of the fourth group are discussed. 相似文献

By the example of ZnSe crystals, the capabilities of two-photon confocal microscopy as a tool for obtaining “planar” maps of nonequilibrium charge-carrier lifetimes in semiconductor materials and for investigating other direct-gap semiconductors and semiconductor heterostructures are considered. It is shown that such maps with a depth step and an in-plane resolution of several microns can be obtained for distances from the surface up to 1 mm. This technique is used to visualize inhomogeneities in the crystals under study and to examine their structure and luminescence characteristics. 相似文献
