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.

f3: Relation between center wavelength of fluorescence spectrum and gain fiber length and typical fluorescence spectrum (inset).

Mentions: The relationship between the length of gain fiber and center wavelength in fluorescence spectrum is shown in Fig. 3 and a typical laser spectrum by using a long gain fiber length such as 30 cm is shown in Fig. 4. By decreasing the gain fiber length, the center wavelength of fluorescence spectrum shifts to short wavelength and a gain fiber with length of 15 cm has been chosen in this experiment for laser output at ~1750 nm. The availability of a narrow-linewidth laser source at ~1750 nm should be benefit for a range of applications, especially in 4.3 μm mid-infrared fiber laser production5.
