Excited-state absorption-enhanced thermal optical limiting in C_60

Enhanced nonlinear absorption and optical limiting in semiconducting polymer/methanofullerene charge transfer films

“…[15][16][17][18][19][20][21][22] Comparable optical limiting was reported for thick layers ͑each several millimeters thick͒ of C 60 in polymethyl methacrylate when pumped on resonance at 532 nm. 23 This research was supported by the U. S. Air Force Office of Scientific Research under AFOSR93-1-0191 ͑Dr.…”

Recent advances in optical limiting properties of fluorinated graphene oxides

“…For example, carbon particle suspensions (CS) show strong optical limiting due to NLS caused by thermally induced microplasma, 35 whereas fullerenes (C 60 ) exhibit robust limiting due to large RSA. [36][37][38] In addition, multiwalled and single walled carbon nanotubes (CNTs) exhibit broadband optical limiting due to NLS 39,40 while GO exhibits limiting due to RSA.…”

Novel, Organically Doped, Sol-Gel-Derived Materials for Photonics: Multiphasic Nanostructured Composite Monoliths and Optical Fibers

“…89 The power limiting action of this multiphase composite was studied at two wavelengths: (1) at 532 nm, a wavelength where C 60 is active due to reverse saturable absorption, 86,90 and (2) at 800 nm, where the dye BBTDOT is active due to two-photon nonlinear absorption. 24,89 The source at 532 nm was a frequency-doubled, Q-switched Nd : YAG laser which delivered 8 ns pulses at a repetition rate of 10 Hz.…”
