Abstract :
Summary form only given. We present new experiments with an Er-doped fiber laser pumped by a low-power 980 nm laser diode. In order to improve the laser stability performance an FBG with bandwidth FWHM /spl sim/12.7 GHz has been specifically employed in the laser configuration. It allowed us to localize the frequency /spl nu//sub A/ near the maximum of FBG reflectivity /spl nu//sub M/ (/spl lambda//sub M/ = 1533.098 nm) and also to prevent the undesirable growth of high-order SBS components during lasing (note that /spl Delta//spl nu//sub SBS/ /spl sim/ 11 GHz). A Q-switched operational mode has been successfully obtained with this configuration at pump power levels of 20-160 mW.
