“…Substantial variations of the laser bandwidth with pump power have been previously reported [38], and intensity fluctuations as well as changes of the mode structure investigated [37], for Yb-doped fiber lasers in Littrow configuration. These dynamical behaviors are reminiscent of those obtained in Er-doped fiber lasers [39,40], but their exact physical origin in Yb-doped fibers may not be yet fully established [30,31,32,37]. Self-pulsing has been demonstrated to be dependent on passive cavity losses and favored at high losses [30,31,41].…”

Large amounts of hyperpolarized 3 He gas with high nuclear polarization rates are required for use in neutron spin filters or nuclear magnetic resonance imaging of human lung. Very high efficiency can be obtained by metastability exchange optical pumping using multimode lasers to excite the 2 3 S-2 3 P transition at 1083 nm. Broadband Ytterbium-doped tunable fiber lasers have been designed for that particular application. Different options for the architecture of the fiber oscillator are presented and compared. Emphasis is given to a linear cavity configuration that includes a high reflectivity fiber mirror and a low reflectivity tunable fiber Bragg grating. Optical measurements are performed to finely characterize the spectral behavior of the lasers. Atomic response is also quantitatively probed to assess the optimal design of the oscillator for optical pumping. Multimode operation matching the 2 GHz Doppler-broadened helium resonance line and tunability over more than 200 GHz are demonstrated. Boosting the output of this fiber laser with a Yb-doped fiber power amplifier, allfiber devices are built to provide robust, high power turn-key sources at 1083 nm for improved production of laser polarized 3 He. 42.55.Wd; 32.80.Bx PACS

“…This behavior has been analyzed by using a rate equation and the origins of the interaction have also been described [11]. One of the origins involves the existence of the Er-ion pairs dispersed in the EDF [9]. With an EDF that has a high Er-ion concentration, the average distance between neighboring Er-ions is small.…”

“…The advantages of the laser are its high frequency stability, narrow linewidth, and an output beam with no additional frequency modulation. However the output power included a small amount of power fluctuation associated with laser relaxation oscillation [9,10]. In addition pulse oscillation started when an erbium-doped fiber (EDF) with high Er-ion concentration was employed in order to obtain high power.…”

Abstract:An erbium-doped fiber laser with a high Er-ion concentration generally causes output power fluctuation and self-pulsing resulting from relaxation oscillation. In this work, we employed a new EDF with high Er-and Al-ion concentrations in order to suppress the relaxation oscillation and increase the output power of the laser. As a result, the output power was more than doubled and the power fluctuation halved. The linewidth was narrowed to 4 kHz. Furthermore the frequency stability of the 13 C 2 H 2 frequency-stabilized erbium fiber laser reached as high as 1.3 × 10 −11 for τ = 1 s and 2.0 × 10 −11 for τ = 10 2 s. The short-term stability of τ = 1 s was also improved.
