Abstract
Optical limiting of nanosecond and picosecond laser pulses through millimeter-length isotropic liquid-crystal-cored fiber structures is reported. Low limiting threshold and clamped transmitted outputs are observed. The underlying nonlinear mechanisms are nonlinear photoabsorptions and scattering and lossy waveguiding caused by laser-induced thermal-density index fluctuations.
