Dy. Stepanov et Gj. Cowle, PROPERTIES OF BRILLOUIN ERBIUM FIBER LASERS, IEEE journal of selected topics in quantum electronics, 3(4), 1997, pp. 1049-1057
The unique combination of two gain media in brillouin/erbium fiber las
ers results in distinctive properties of such sources, This paper desc
ribes in detail the output and efficiency properties of brillouin/erbi
um fiber lasers, from experimental results and a theoretical model. Si
ngle longitudinal mode output with linewidth <10 kHz was measured, wit
h a 4-nm tuning range with the brillouin pump wavelength, Frequency pu
lling associated with the brillouin gain was investigated and observed
to increase linearly with the brillouin pump power.
