Abstract :
We experimentally research the spectral and temporal properties of a multiwavelength erbium-doped fiber laser based on a nonlinear amplifying loop mirror (NALM). The laser can work in two multiwavelength lasing states by switching the transmission function of the NALM. One state corresponds to the passively mode-locked operation, presenting 78 stable lasing wavelengths and nanosecond-square pulses. The other state is the continuous-wave operation with four tunable lasing wavelengths with narrow linewidth and high signal-to-noise ratio.
