摘要: Abstract We present synthesis of Cobalt nanoparticles dispersed in toluene by laser ablation and their optical limiting properties with nanosecond pulses. Absorption spectra concentration dependent studies on indicate it as a versatile limiter. show better compared to the reference limiter fullerene C 60 . Optical threshold is about three times less than that Z-scan experiments, angle scattering, intensity transmission, temporal profile measurements non-linear absorption, nonlinear scattering thermal refraction are responsible for behavior nanoparticles.
