| 摘 要： | 在研究了短光纤(L～L_w)中受激喇曼散射的斯托克斯脉冲对基波脉冲能量箝位效应的基础上进行了脉冲压缩实验。以高泵浦功率(P=1600W)注入长度为8.95m绿光单模光纤中,采用双光程的光栅对压缩结构,并引入空间频率窗口滤除自相位调制光谱的非线性啁啾部分,将40ps的锁模Nd:YAG倍频光脉压缩至<5ps。

| Abstract: | Pulse compression experiment was conduc-ted by studying the clamping effect of stokes pulses in SRS of short optical fiber (L≈Lw) on pulse energy of fundamental wave. With the high pumping power (P = 1600W) injecting into a 8.95m long monomode optical fiber for green light, moda-looked and frequency doubled NdrYAG laser pulse of 40 ps was compressed to have the duration of less than 5ps (due to the limitation of temporal resolution of the streak camera), by employing the configuration of a pair of grating with double optical path length, and filtering out the portion of nonlinear chirp of SPM spectrum with the spatial frequency window. |
