| 摘 要： | 本文给出掺Ｙｂ光纤脉冲放大的实验结果,在一段长１８ｍ的Ｙｂ光纤中获得了超过２６ｄＢ的增益．利用１．０５３μｍ单模ＬＤ激光器作注入信号．重复频率为１ｋＨｚ,脉宽分别为１μｓ、２μｓ、５μｓ、１０μｓ．增益与泵浦功率等关系的实验结果表明增益对泵浦功率、光纤长度和信号功率敏感。当小信号放大时,输出脉冲不失真,表明该放大器可用于高脉冲能量激光的前置放大．

| Abstract: | In this paper experimental results on the pulse amplification using Yb doped fiber amplifier were given, gain over 26 dB was obtained on 18 m Yb-doped fiber, and the single mode LD laser at 1.053 μm was used as the injected signal modifying with repeat rate at 1 kHz and the pulses vary with 1 μs, 2 μs. 5 μs, 10 μs. The results of the relationship between the gain and the pump power and other relative relationship, show that the gain is sensitive about the pump power, the length of fiber, and also about the signal's power, and with small signal amplification, the output pulses have not been distorted this show the equipment can be used as the front end of the huge pulse energy laser. |
