| 英文摘要 | a comparative research on saturable absorption (sa) behavior dependence on wavelength and pulse duration was performed for graphene polymer composites. free-standing graphene-polyvinyl alcohol (pva) composite films were fabricated by using solution cast method in combination of liquid phase exfoliation. sa responses were observed by using an open-aperture z-scan technique for 340 fs pulses at 1030 nm and 515 nm from a mode-locked fiber laser, and 6 ns pulses at 1064 nm and 532 nm from a q-switched nd: yag laser. the graphene films possess better sa property, i.e., larger sa coefficient and figure of merit (fom), and lower saturation intensity is, for ns pulses than that for fs pulses at the similar near infrared (nir) wavelength. for fs pulses, the films show better sa response at 1030 nm than that at 515 nm. by employing slow and fast sa modelling, the excited state and ground state absorption cross sections were estimated to be similar to 10-17 cm(2), and the ratio was similar to 0.6 at nir for both fs and ns pulses.
