| | | Article Name : | | | Self Q-switched wavelength tunable ErbiumYtterbium co-doped double clad fiber laser | | Author Name : | | | I. M. BABAR1, M. YASIN | | Publisher : | | | Bridge Center | | Article URL : |  | | | Abstract : | | | An Erbium-Ytterbium co-doped double clad fiber Q-switch
wavelength tunable laser based on self Q-switching principle is
proposed in a simple ring cavity configuration. This laser doesn’t
employ any component like polarization controller, fiber bragg grating,
un-pumped fiber section, Mach-Zehnder interferometer and saturable
absorber as is usually used to produce Q-switch lasers. This laser is
successfully tuned in the range 1535-1550nm by using OTF-320
manually tunable optical filter. We observe a stable Q-switch laser in
the range 1535 to 1550nm, with pulse energy of 17nJ at 1445 nm. An
increase in repetition rate is observed from 31.53 to 35.64 KHz with
increase in the filter wavelength from 1535 to 1550 nm. | | Keywords : | | | Self Q-switch, tunable filter, double clad fiber, ring cavity. |
