摘要註:	實驗中使用980nm雷射激發摻鉺光纖產生在範圍1525 nm ~ 1565 nm寬頻光源，同時也做為光纖環型雷射架構放大器用途，環型迴路中添加兩種不同頻寬的濾波器，並且使用電光調變器(eletro-optical modulator)對光纖環型雷射作調變，達到主動鎖模之目的產生超短脈衝雷射。比較兩種不同頻寬的濾波器，以fliter (13.4nm)為架構時，調制頻率操作在3.73GHz，脈衝寬度為48ps；以FBG(0.1~0.2nm)為架構時，外部調制頻率操作在3.202GHz，脈衝寬度為156ps。另外在實驗中也將EDF當作光開關控制介質，輸入可調雷射做為控制光源(control light)，來控制環型雷射光訊號(signal light)，形成可以單純利用光來控制環型光纖鎖模雷射的輸出，其最高調制頻率可達到1kHz，同時我們也研究EDF對不同波長的控制光訊號吸收效率的不同，造成光開關啟動能量之差異。 In this thesis we used a erbium-doped fiber which is pumped by a 980 nm laser diode to achieve a profile covered from 1525 nm to 1565 nm. At the same time the EDF be used to amplify the signal in a fiber ring laser system,and add two different bandwidth filters.Add an electro-optical modulator be used to study the effects of fiber ring laser mode -locking characteristic.Comparing two different bandwidth filters, Stable mode-locking with a pulse width of 48 ps was achieved at 3.73 GHz modulation frequency (filter:13.4nm). Stable mode-locking with a pulse width of 156 ps was achieved at 3.202 GHz modulation frequency(FBG:01.~0.2nm).The EDF also be used as a optical switch in the experiment.The tunable laser light (control light) be used to control the ring laser signal (signal light), and we can simply use light to control the output of fiber ring laser. The highest modulation frequency is up to 1kHz, We also study EDF which have different absorption for different optical signal,and the optical switch have influence for different energy.
