Effect of shock loading on transparency of sapphire crystals

摘要

Singlehyphen;crystal sapphire was found to lose some of its original transparency in the near infrared (0.9 mgr;m) when subjected to strong dynamic compression in the pressure range between 100ndash;130 GPa (1ndash;1.3 Mbar). Experimental evidence of this phenomenon is presented and discussed in relation to some of the other known properties of the crystal.
