Broadband optical limiting with multiwalled carbon nanotubes

Abstract

Optical limiting effects in multiwalled carbon nanotubes have been observed in the visible and infrared spectral regions with nanosecond laser pulses. The multiwalled carbon nanotubes investigated include those suspended in distilled water and embedded in polymethyl methacrylate films. Among all the samples measured, the limiting performance of the carbon nanotube suspension is the best with the limiting threshold determined to be ∼1, 5, and 13 J/cm2 at 532, 700, and 1064 nm, respectively. The possible mechanism for the observed effects is discussed.

Optical limiting in single-walled carbon nanotube suspensions

“…Like in C 60 and other fullerene derivatives, optical limiting is an important application of nanotubes. Optical limiting in liquid suspensions of multi-walled carbon nanotubes ( MWNTs ) has been reported recently [5,6]. The observed limiting has been compared with that of its well-studied cousin C 60 fullerene.…”

Tungstate fluorophosphate glasses as optical limiters

“…1,2 Various phenomena are exploited for OL, such as nonlinear absorption and nonlinear refraction, [1][2][3][4] nonlinear light scattering, 5 and polarization changes, 6 among others.…”

Recent advances in optical limiting properties of fluorinated graphene oxides

“…For example, carbon particle suspensions (CS) show strong optical limiting due to NLS caused by thermally induced microplasma, 35 whereas fullerenes (C 60 ) exhibit robust limiting due to large RSA. [36][37][38] In addition, multiwalled and single walled carbon nanotubes (CNTs) exhibit broadband optical limiting due to NLS 39,40 while GO exhibits limiting due to RSA.…”
