Thus , 21mj of single pulse energy has been obtained . in the case of 10 % reflectivity , less than 3 . 7ns with 8 . 6 : 1 pulse - compression ratio has been observed 应用200 m光纤获得了21mj的四通放大输出能量并在能量反射率10的情况下获得了高达8 . 6倍的脉冲压缩比。
Applying 200 m quartz fibers in the ld - pumped laser system with double - pass configuration , 57 % sbs reflectivity , near 92 % sbs fidelity and 85 % relative stability have been obtained . and high beam quality of phase - conjugated laser close to that of oscillator has been achieved 应用200 m光纤经双通放大最高可获得57的能量反射率、 85的相对稳定性以及92的相位共轭保真度,并观察到激光系统的输出光束质量被显著改善。
In addition , a new type of phase conjugator using tapered fiber is designed , which combined the higher reflectivity of small core - diameter fiber and higher damage threshold of large core - diameter fiber . the theoretical analysis has also been carried out in section iv . applying it in double - pass system , the maximum sbs reflectivity arrives at 85 % and relative stability arrives at 90 % , which is more than that of common optical fiber phase - conjugator 为了获得更高的能量反射率和稳定性,我们自行设计了一种新型的锥度光纤,并应用于ld泵浦的双通放大dpl系统中;实验表明:应用锥度光纤相位共轭器可以获得高达85的能量反射率和90的相对稳定度。
