Influence of dislocations on the characteristics of laser screens made of CdS

The characteristics of a laser screen made of CdS and operating at 80 °K were investigated as a function of the density of growth dislocations in the range 5×10 – 2×10⁷ cm^–2 and of mechanically introduced dislocations with densities up to 6×10⁷ cm^–2. The influence of the dislocation density on the characteristics of a laser screen operated at high excitation rates was found to depend on the state of the broken bonds but not on the nature of dislocations.
