摘要：
We demonstrate a simple erbium-ytterbium co-doped fibre laser with dual-wavelength output, which operates at 1064 and 1534 nm using a single gain medium. The laser operates on a recently developed erbium-ytterbium doped fibre (EYDF) with the erbium and ytterbium ion concentrations of 1000 and 1500 ppm respectively, in conjunction with a linear cavity setup based on two fibre Bragg gratings. By pumping a 5 m long EYDF with a 980 nm laser diode, simultaneous generation at 1064 and 1534 nm is reached, with the corresponding peak powers of 3.4 and -8.3 dBm. The lasing thresholds are 40 and 80 mW respectively for 1064 and 1534 nm.
