Abstract

A wavelength and bandwidth tunable filter and its application in a dissipative soliton (DS) Yb-doped fiber laser are demonstrated. The spectral filter consisting of six cascaded temperature-sensitive long-period fiber gratings is designed and fabricated for the first time, to the best of our knowledge. The corresponding spectral characteristics of the filter are also characterized with temperature. Its 3-dB bandwidth can be adjusted from 4.84 to 11.02 nm, and the center wavelength is continuously adjustable from 1036 to 1045 nm. The sensitivity of the variation of the center wavelength and the linearity of the center wavelength variation are 32 pm/°C and 99.53%, respectively. This home-made spectral filter has two notable features: i) with regard to the tunable spectrum, the 3-dB bandwidth of the spectrum filter can be unchanged; ii) with regard to the spectral tunability, the 3-dB bandwidth of the spectral filter can also be quantitatively changed as needed by changing the heating mode. The home-made spectral filter is used in the DS fiber laser to further realize the continuous adjustment of DS with a tuning accuracy of 0.03 nm by a step size of 1°C. Such a wavelength-tunable DS fiber laser greatly enhances the design flexibility of the coherent anti-Stokes Raman scattering source.

NameDescription
Supplement 1       The spectra of the LPFGs in the CLPFGs and the excellent stability during the heating process.
Visualization 1       As the temperature of the spectral filter increases, the overall pulse spectral range shifts toward longer wavelengths. As the temperature of the spectral filter decreases, the overall pulse spectral range shifts toward shorter wavelengths.
Visualization 2       The temperature at the short-wavelength grating of the spectral filter is reduced, then the temperature at the long-wavelength grating of the spectral filter is increased, and the overall pulse spectral range is broadened to both long and short wavel
