Abstract
We report a novel narrow line width single longitudinal mode random laser at wavelength of 1550 nm. The laser is based on Rayleigh backscattering in a standard single mode fiber (SMF-28e) as a distributed mirror [1,2], and the semiconductor optical amplifier (SOA) as the gain medium. The optical signal to noise ratio was measured to be 34 dB. The line width of the laser was observed to be monotonically increasing with SOA bias current. The minimum line width of the laser was measured to be 6.5 KHz at SOA current of 170 mA. The maximum value of optical power was measured to be 4 mW.
