We investigated the resonance dependence of saturable absorption (SA) properties in near-infrared in single-wall carbon nanotube (SWNT) materials prepared by the laser ablation method. For SWNT thin films coated on glass plates with a distinct single absorption band centered at 1.78 μm, we measured SA properties using the z-scan method with just- or weak-resonance excitation using a femtosecond laser at 1.78 μm or at 1.55 μm, respectively. In the just-resonance experiments the laser intensities of ${\sim}50$ MW/cm2 induced decreases in the absorption coefficient by ${\sim}40$%, but in the weak-resonance experiments one-order-higher laser intensities were necessary to obtain absorption changes of similar extents.
