腔内非线性压缩直接产生超短脉冲

Direct ultrashort pulse generation by intracavity nonlinear compression

L. M. Zhao, D. Y. Tang, T. H. Cheng

摘要:

从理论和实验上观察到在激光谐振腔中直接产生超短、变换极限脉冲。这构成了一种新的类型的超短脉冲产生锁模激光器:在众所周知的孤子(双曲正割类),色散管理孤子(高斯类),抛物线脉冲加上外部压缩,超短脉冲的解决方案,描述脉冲在激光腔中的演化的非线性波方程观察。稳定的超短、变换极限脉冲存在于比放大器的增益带宽更宽的光谱中,这对于其他激光器具有实际应用。

英文摘要:

Direct generation of ultrashort, transform-limited pulses in a laser resonator is observed theoretically and experimentally. This constitutes a new type of ultrashort pulse generation in mode-locked lasers: in contrast to the well-known solitons (hyperbolic secant like), dispersion-managed solitons (Gaussian-like), and parabolic pulses plus external compression, ultrashort pulse solutions to the nonlinear wave equations that describe pulse evolution in the laser cavity are observed. Stable ultrashort, transform-limited pulses exist with optical spectrum broader than the gain bandwidth of the amplifier, and this has practical application for other lasers.
