Abstract
We demonstrate a highly efficient, stable, and tunable dispersive wave (DW) emitted by the soliton in a tellurite microstructured optical fiber. The dependence of the generated DW properties on the average pump power is experimentally investigated. By using the 80-MHz pulse emitted from an optical parametric oscillator as the pump source, the DW from ~1626 to 1685 nm is obtained with the average pump power changing from ~250 to 440 mW at the pump wavelength of ~1760 nm. The conversion efficiency is over ~65%. The full width at half maximum (FWHM) of DW pulse at the center wavelength of 1626 nm is ~90 fs, which was measured by an intensity autocorrelator. The stable DW pulse can be used as a near-infrared femtosecond source.
