Abstract

Experiments on supercontinuum generation in high pressure CO₂ (1 - 40 atm) by 1 ps pulses at 593 nm are described. While changing the gas pressure and the laser power we observed self-focusing and optical breakdown in the gas. Their influence on the supercontinuum spectral width evolution is experimentally demonstrated and discussed. Threshold powers for optical breakdown and supercontinuum generation have been measured under different focusing conditions. The relation between these phenomena is analyzed.
