摘要

A short-cavity Er/Yb-P/AI/Si co-doped fibre grating laser is demonstrated, with a pair of fibre Bragg gratings whose central resonant wavelengths are around 1551 nm and the reflectivities are 10.5 and 15dB. The threshold value is about 48mW and the slope efficiency is 1.1%. The signal-to-noise ratio is 59dB, and the output central wavelength is 1550.94 nm. A peak power of 1.112mW at a pump power of 80mW has been achieved.
