Abstract
We present a single-shot damage threshold measurement and modeling for fuse d silica at 800 nm as a function of pulse duration down to 20 fs. We examin e the respective roles of multiphoton ionization, tunnel ionization, and im pact ionization in laser damage. We find that avalanche predominates even i n the case of sub-100-fs pulses.
