Impact Statement:
We first demonstrated an EDF ring laser scheme with wavelength-upconverted output and single-longitudinal-mode (SLM) oscillation. In the demonstration, the lasing wavelength could be upconverted to 1554.30, 1558.37 and 1562.83 nm owing to the nonlinear effect, when the initial Bragg wavelength of FBG was nominated at 1544.04, 1535.98 and 1531.79 nm, respectively.
Abstract:
In this paper, we present experimentally an erbium-doped fiber (EDF) laser system to accomplish the single-longitudinal-mode (SLM) and wavelength-upconverted output by using nonlinear effect. To accomplish the SLM output, a short length of unpumped EDF saturable absorber (SA) is applied inside the EDF laser cavity for filtering densely multi-mode noise. In accordance with the designed EDF laser system, the lasing wavelength can be upconverted to a longer wavelength position. In addition, the output characteristics of output power, optical signal to noise ratio (OSNR), tunability, stability and linewidth in the EDF laser are also discussed.
