Multiwavelength birefringent-cavity mode-locked fibre laser

摘要

Generation of simultaneous four wavelength optical pulses is successfully demonstrated using a novel multiwavelength mode-locked Er/sup 3+/-doped fibre ring laser with two, 45 degrees concatenated, birefringent fibres in the cavity. Wavelength separations of 0.9-2.7 nm and pulse durations of 28-55 ps are obtained.
