An erbium-doped fiber laser based on a microsphere coupling system was discussed.The proposed fiber laser employed a piece of 1.5 m-long erbium-doped fiber, and pumped by 980 nm diode.At the output end of the laser, a coupling system consisted of a silica microsphere with a diameter of 125 m and a fiber taper with a waist diameter of 3 m were introduced.The microsphere acted as both reflective mirror and wavelength selective filter in the laser.The laser was operated with a stable lasing of 1 563.95 nm.The fiber laser was found have huge potential application in high-sensitivity refractive index sensor field.
