Nonlinear Absorption and Ultrafast Dynamics of Ag Nanoparticle

Nonlinear Absorption and Ultrafast Dynamics of Ag Nanoparticle

Resonant nonlinear optical absorption of silver nanoparticles was studied experimentally via open aperture Z-scan using 130 fs, 400 nm laser pulses. Experimental results show that, at low laser intensity, silver nanoparticles can exhibit saturated absorption. While at high laser intensity, it shows...
