| Description | Journal: Laser Physics Letters A wavelength-switchable femtosecond pulse fiber laser is demonstrated by using a saturable absorber (SA) of silica-encased gold nanorods $(GNRs@SiO_{2}$). The $GNRs@SiO_{2}$ SA presents a modulation depth of 4.5% and nonsaturable loss of 32.1%. By properly adjusting the cavity parameters, femtosecond mode-locked pulses centered at 1535.6 nm and 1560.5 nm could be achieved alternately. The durations of pulses at the two wavelengths are measured to be ~403 fs and ~426 fs, respectively. The achieved results indicated that the $GNRs@SiO_{2}$ could indeed be a promising nonlinear material with excellent photothermal stability and saturable absorption, which could satisfy the requirements for different photonic devices and applications. |
