| 英文摘要 | Copper(II) chalcogenide nanocrystals, including Cu2-xY (Y = S, Se, and Te), have an intense localized surface plasmon resonance (LSPR) band in the near-infrared (NIR) region. In this research, colloidal Cu2-xSe@Cu2-xS nanorods were synthesized using the organometallic colloidal and cation-exchange methods. The dynamics of LSPR were investigated using ultrafast laser pulses via pump-probe experiments in the NIR region. Investigation of the transient absorption spectra revealed an LSPR spectral band from approximately 850 to 1350 nm, with a center wavelength of 1030 nm. The kinetics of the recovering plasmon maximum, probed at the peak wavelength of 1030 nm, exhibited a strong nonlinear response for plasmonic absorption, with a modulation depth exceeding 25% in the transmitted signal under a pump fluence of 3.97 mJ/cm(2). The ultrafast nonlinear optical properties of these plasmonic nanoparticles could be used as excellent saturable absorbers (SAs) in ultrafast lasers. A compact passively Q-switched Yb3+: YAG microchip laser with a Cu2-xSe@Cu2-xS SA was investigated. Furthermore, a maximum average output power of 187 mW was obtained, with a pulse energy of 4.11 mu J, pulse duration of 8.5 mu s, and repetition rate of 45.45 KHz at a pump power of 8.7 W. |
