|Title:||Characterization of a dual wavelength fibre laser based-on dumbbell configuration||Authors:||Abdullah, F.
|Issue Date:||2004||Abstract:||This paper reports the design of a dual wavelength fibre laser system using a dumbbell shaped configuration. The oscillation of the lasing wavelength is completed via fibre loop mirrors with a tuneable bandpass filter. The output power, side mode suppression ratio and wavelength spacing of the lasers were investigated against the pump power for forward and backward pumping schemes. The output powers of 4.99 and 3.69 dBm at 1545.08 and 1547.28 nm, respectively, for forward pumping scheme. On contrary, the output powers of 1.93 and 2.14 dBm at 1546.12 and 1551.48 nm, respectively, for backward pumping scheme. The peak output powers of less than 1 dB difference are obtained without any adjustment of the intra-cavity loss over a wider spectral range. © 2003 Published by Elsevier Ltd.||URI:||http://dspace.uniten.edu.my/jspui/handle/123456789/8721||DOI:||10.1016/j.optlastec.2003.08.003|
