Laser pulse turns glass into a metal
Vienna, Italy (SPX) Aug 28, 2014 - Quartz glass does not conduct electric current, it is a typical example of an insulator. With ultra-short laser pulses, however, the electronic properties of glass can be fundamentally changed within femtoseconds (1 fs = 10^-15 seconds). If the laser pulse is strong enough, the electrons in the material can move freely. For a brief moment, the quartz glass behaves like metal. It becomes op ... more
