Abstract:光纖雷射可應用於醫療手術、材料加工、大氣感測等各種不同領域,近年來光纖雷射波長往長波長的方向發展,2 µm的波段對有人眼安全的特點。目前摻銩(Tm3+)光纖雷射常用於2µm,但銩離子最長可以釋放出2.05 µm的波段,而為了產生更長的雷射波段,我們研究高濃度摻鈥矽酸鹽光纖。實驗中,應用2.06 µm Tm:Ho:YLF固態雷射系統,做出摻鈥光纖雷射放大器。我們以清華大學施宙聰教授實驗室研發出單頻波長可調的2.06 µm Tm:Ho:YLF固態雷射系統當作種子光源,再加上本實驗室對摻鈥光纖雷射高功率之幫浦光源的相關研究基礎,將Tm:Ho:YLF固態雷射系統和光纖雷射系統做結合,並後續做出摻鈥光纖幫浦雷射放大器,並研究高濃度摻鈥矽酸鹽光纖之單位長度增益。
Translated Abstract:Fiber laser can be used in medical surgery, materials processing and gas sensing. Recently, more and more fiber laser research are focused on the long wavelength NIR fiber laser sources. The 2µm fiber laser owns the eye-safe feature. The thulium fiber laser has been actively studied for 2µm emission, but the longest wavelength of the thulium ion can only be 2.05 µm. To extent the laser operation wavelength, in this thesis, we investigate the gain property of heavily Ho3+ doped silica fibers, based on a Ho3+ doped fiber MOPA. The seed source is a wavelength-tunable single-frequency 2058nm Tm:Ho:YLF solid state laser, built by Prof. J.T. Shy and P.L. Luo at NTUT. Combined with our own pump source, a Tm3+ doped fiber MOPA, we successfully measure the gain per unit length of the heavily Ho3+ doped silica fiber.
