Abstract

We proposed a room temperature stable dual wavelength Erbium-doped Zirconia fiber (EDZF) based fiber laser using a polarization maintaining fiber(PMF) that cascaded with the polarization –insensitive 3dB coupler as the wavelengthselective filter in a ring configuration. Two simultaneous lasing lines at 1565.5 nm and 1567.2 nm were obtained by adjusting a state of polarisation inside the cavity with peak powers of 0.17 mW and 0.18 mW respectively at the maximum pump power of 120 mW. Both lasing lines have a signal to noise ratio of more than 30 dB and threshold pump power of about 30 mW. The fluctuation of wavelength and peak power is less than 0.1 nm and 0.1 dB over 1.5 hours, which indicates an excellence stability of the proposed laser.
