1.5 μm Fiber Ethane Gas Raman Laser Amplifier
A 1.5 μm fiber gas Raman laser amplifier based on the hollow core fibers is reported. In the experiments, a 1.5 μm tunable distributed feed back laser is used as a seed. The output continuous wave seed laser, together with the output pulse pump laser of a 1064 nm microchip laser, is coupled into the ethane-filled hollow core fiber by using a dichroic mirror, and then efficiently generated 1553 nm Raman laser by stimulated Raman scattering of ethane gas. With the injected seed laser, the Raman scattering threshold is significantly decreased and the Raman conversion efficiency increases to 47.5%. This study provides an effective technical avenue to achieve the efficient fiber gas Raman laser output.
