Abstract: A method for stabilising the radiation wavelength of a mode-locked fibre nanosecond laser is proposed and realised. Generation of nanosecond laser pulses with a spectral bandwidth of 50 MHz, which corresponds to a transform-limited pulse, is demonstrated.

Keywords: optical fibre, fibre laser, nanosecond pulses, passive loop mirror, transform-limited pulse.
