Quan Z, Gao C, Guo H, Wang N, Cui X, Xu Y, Peng B, Wei W - Sci Rep (2015)

Bottom Line: A type of Tm-doped silica fiber laser with narrow-linewidth and output wavelength near 1750 nm was firstly presented, by using a 1550 nm Er-doped fiber laser pump source and a volume Bragg grating (VBG).By means of a 15 cm Tm-doped fiber, a 400 mW continuous wave (cw) at ~1750 nm with FWHW of ~54 pm was generated, corresponding to an average slope efficiency up to 23.5% with respect to absorbed pump power.All experimental results demonstrate that this fiber laser will be an effective and promising pump source for mid-IR laser output.

ABSTRACT
A type of Tm-doped silica fiber laser with narrow-linewidth and output wavelength near 1750 nm was firstly presented, by using a 1550 nm Er-doped fiber laser pump source and a volume Bragg grating (VBG). By means of a 15 cm Tm-doped fiber, a 400 mW continuous wave (cw) at ~1750 nm with FWHW of ~54 pm was generated, corresponding to an average slope efficiency up to 23.5% with respect to absorbed pump power. The influence of gain fiber length on the spectrum wavelength has been investigated in detail. All experimental results demonstrate that this fiber laser will be an effective and promising pump source for mid-IR laser output.

f2: Laser output with VBG compared to fluorescence output without VBG (a) and optical spectrum of laser output at 1749.62 nm (b). Both of the input powers were 6 W.

Mentions: Different spectra under two circumstances (with and without VBG) are measured in Fig. 2. It shows that the fluorescence without VBG has a bandwidth of ~200 nm centered at 1850 nm. The laser with VBG for wavelength selection with spectral FWHM of 54 pm laser spectrum centers at 1749.62 nm.
