Absorption coefficients measured at 5 to 6 and 10.6 pm by CO- and CO2-laser calorimetry of TICl, KRS-6 (TICl-TlBr), TlBr, and KRS-5 (TlBr-TlI) crystals are found to increase upon irradiation with 60Co γ-rays. It is found that the radiation resistanc

Polycrystalline waveguides with diameters of 500 μ were extruded from KRS-5 and KRS-6 crystals. A reduction in the average grain size to 3 μ made it possible to ensure that the minimum bending radius was 1 cm. The lowest optical losses in a wavegui
