Abstract
We report here the characteristic of a 1.55-μm fiber gas Raman amplifier worked in an ethane-filled hollow-core fiber (HCF). This amplifier is composed of a CW C-band tunable, narrow linewidth seed laser, and a pulsed 1064.6-nm microchip pump laser. Through a dichroic mirror, the seed laser, together with a 1064.6-nm pump source, is coupled into the ethane-filled HCF and then efficient 1553-nm Raman laser generates by the stimulated Raman scattering of ethane molecules. A maximum Raman laser average power of 43.8 mW (pulse energy 87.6  μJ) with a Raman conversion efficiency of 47.5% (quantum efficiency of ∼70  %  ) is obtained using 8.7-m HCF filled with 1.4-bar ethane. A method to obtain efficient 1.55-μm fiber laser sources is demonstrated.
