Paper Abstract

We report experimental observations of temporal pulse-shape distortion in 1.7 ns 10.6-μm laser pulses passing through the multiphoton saturable absorber SF6 and an SF6-based fluorocarbon mixture. The observed effects include a lengthened risetime, delays in peak onset times, and a decrease in the pulse falltime which tends to symmetrize an input triangular pulse. The pulse-shaping effects are seen over a wide range of wavelengths, fluences and gas pressures. Qualitatively similar effects are predicted by a two-level saturable absorber model in an appropriate parameter space.
