摘　　要：文章论述了基于注入锁定增益开关调制法布里-珀罗半导体激光器(FP-LD)的波长连续可调脉冲生产技术.包括两方面的内容:1自激注入锁定FP-LD系统以获得波长连续可调脉冲输出,在48 nm波长范围获得37 dB以上的边模抑制比(SMSR),重复频率为2.5 GHz;2带有波长选择反馈环的外注入锁定FP-LD系统以获得波长连续可调脉冲输出.在20.4 nm的波长调节范围内获得31 dB以上的边模抑制比(SMSR).系统结构简单,可工作在任意重复频率上.In this paper , Fabry-P＆#233;rot laser diode （ FP-LD） based pulse generation with wavelength continuously tunable is demonstrated .Two topics are focused including ① a self-seeding system for continuous and widely wavelength-tunable optical short pulse generation .The side mode suppression ratio （SMSR） of greater than 37 dB is achieved across the wavelength range of 48 nm, at a constant repetition frequency of 2.5 GHz;②an ex-ternal-injection seeding scheme with selected wavelength feedback to the master FP laser diode for wavelength tunable optical short pulse generation .SMSR higher than 31 dB over a wavelength tuning range of 20 .4 nm have been obtained .The system is simple , and can be operated at arbitrary repetition frequency .
