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.

f1: Evolution of output power at 1750 nm laser as linear function of absorbed (top scale) and incident (bottom scale) pump powers at 1550 nm.

Mentions: Laser output power as a function of absorbed and incident pump power is illustrated in Fig. 1. It is found that the laser reached threshold at an absorbed pump power of about 600 mW and generated a maximum output power of 400 mW, corresponding to an average slope efficiency of 23.5% with respect to absorbed pump power.
