Abstract

We examine optical limiting with C₆₀-toluene 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 self-defocusing. 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 micrometers .
