碩士 === 國立臺北科技大學 === 光電工程系 === 107 === Recently, light sources around 2m, which were called eye-safe wavelength region have been attracted considerable interest and have been uesd in the fields of medicine, industry, remote sensing and so on. In this thesis, semiconductor saturable absorber mirrors (SESAMs) are used as the saturated absorber of mode-locked fiber lasers, and narrow-band FBGs are used to form passive mode-locked fiber lasers with linear cavity. In order to create a stable mode-locked fiber system with high efficiency, high energy and large operating region, we design and analyze the passive mode-locked fiber laser systems with different laser parameters. We have successfully demonstrated narrow-linewidth mode-locked lasers with nJ class of pulse energy and operating wavelength of near 2 μm. In addition, we have verified important parameters for passive mode-locked lasers by based on both SESAMs and FBGs.
