Du. Noske et al., DUAL-WAVELENGTH OPERATION OF A PASSIVELY MODE-LOCKED FIGURE-OF-8 YTTERBIUM-ERBIUM FIBER SOLITON LASER, Optics communications, 108(4-6), 1994, pp. 297-301
Stable, dual-wavelength operation of a diode-pumped, passively mode-lo
cked, ytterbium-erbium ''figure-of-eight'' (F8L) fibre laser has been
achieved by including tunable filters and/or fibre gratings in the las
er cavity. The centre wavelengths of the two channels were independent
ly tunable when gain compensation was provided in the cavity. Bandwidt
h-limited solitons could be generated.
