The saturable absorption (SA) properties of boron nitride encapsulated single walled carbon nanotubes (BNNT@SWCNT) at 2.3 μ m were measured using an open aperture z-scan method and compared to those of pristine SWCNTs. The SA properties of both nanotube samples were found to agree within the experimental uncertainty.
Both BNNT@SWCNT and pristine SWCNT had an absolute modulation depth of 10% and a normalized modulation depth of 83%. The saturation fluence of BNNT@SWCNT was found to be 29±5 μ J/cm2 and the saturation fluence of pristine SWCNT was 25±5 μ J/cm2.
This result suggests that the BNNT@SWCNT inherits the non-linear optical properties of SWCNT, which make it suitable for modelocking at mid-infrared wavelengths, while taking advantage of the higher damage threshold of BNNT@SWCNT.
