Abstract:

Laser induced damage of ZnSe, CdTe, Ge, KRS-5, KCl, NaCl, and BaF₂ single crystals was investigated with the pulsed CO, CO₂, HF, DF, Nd³⁺YAG lasers, as well as repetitively pulsed CO and CO₂ lasers. Physical and mathematical models of destruction of transparent dielectrics and semiconductors were developed. The laser-radiation tolerance of IR materials was found to correlate with the fundamental characteristics: refractive index, bandgap, spectral range, crystal lattice energy, anionic and cationic radii, and the element number in the Periodic Table.
