The authors demonstrate a mode-locked Nd:fibre laser working at 910 nm incorporating a phase biased non-linear loop mirror. The broadest spectral width of the pulse is 11.9 nm and the output power is 20 mW with 450 mW pump power. The dechirped pulse width is 206 fs. To the best of authors' knowledge, this is the first demonstration of a 900 nm femtosecond neodymium fibre laser based on a non-linear...
Green-light-enhanced super-continuum generation which covers the range from 500 to 1600 nm with a strong peak at 530 nm in a tapered photonic crystal fibre with pump pulse energy as low as 280 pJ from a mode-locked Yb:fibre laser is reported. By the f-to-2f self-reference technique, a 27 dB fceo signal was detected using the frequency pair at the Yb:laser wavelength (~1060 nm) and this green light...
