Multiwavelength half-linear cavity Brillouin erbium fiber laser (BEFL) has been demonstrated. The half-linear cavity BEFL is formed by utilizing only two circulators: one circulator acts as input and output ports and the other circulator is used to form a physical mirror. This design exhibits low peak power difference between the adjacent channels, which is about 0.8 dB. At Brillouin pump (BP) power of 5 dBm and erbium doped fiber (EDF) pump power of 90 mW, up to 19 channels over a wide range of 40 nm (1529 nm to 1569 nm) have been obtained. These channels are free from self lasing cavity modes and for the first twelve Stokes lines, the optical signal to noise ratio (OSNR) is approximately higher than 20 dB.
