Efficient distributed feedback erbium-doped germanosilicate fibre laser pumped in the 520 nm band
We demonstrate that the efficiency of short cavity single frequency erbium-doped fibre lasers can be dramatically increased by pumping in the green absorption band. For a 10 cm distributed feedback erbium fibre laser pumped at 523.5 nm, a slope efficiency of 10% is achieved, compared to 1% efficienc...
