Abstract: An all-fibre pulsed fibre laser system emitting at a wavelength of 1093 nm with an average output power up to 10 W is presented. The system is assembled according to the master oscillator/fibre amplifier scheme. Pulses were generated with passive mode locking due to nonlinear polarisation rotation in a standard single-mode fibre. The main fibre amplifier was pumped by fibre-coupled semiconductor laser diodes at a wavelength of 976 nm with a maximum total power up to 50 W . The measured pump duration did not exceed 60 ps at a pulse repetition rate of about 1 MHz . The pulse energy was μ 10 μ J .
