Abstract
We examine optical limiting with Co4oluene for nanosecond optical pulses at 532 nm. When the input fluence is less than 50 J/cm2, optical limiting is due to a combination of reverse saturable absorption (excited state absorption) and selfdefocusing. Nonlinear scattering was not observed. For a peak input fluence greater than 50 J/cm2, an acoustic report and broad-band emission indicate that optical breakdown occurs. We find C60-tetrahydronaphthalene to be a better optical limiter, at 532 nm, than tetrahydronaphthalene solutions of C76, C78, or C84. C84-tetrahydronaphthalene is shown to be an optical limiter at 1. 064 μm.
