Abstract

We report here the first demonstration of a mode-locked fiber laser delivering parabolic pulses (similaritons) at 1534 nm. The use of a Raman-based gain medium potentially allows its implementation at any wavelength. The 22nJ output similariton pulses have a true parabolic shape both in the time and spectral domains and a linear chirp. Linear recompression close to Fourier limit is demonstrated allowing us to obtain 6 ps compressed pulses with a compression factor of 75.

摘要

我们在此报告首次展示了一种锁模光纤激光器，它在1534纳米波长下产生抛物线脉冲（类孤子）。使用基于拉曼的增益介质有可能使其在任何波长下实现。输出的22纳焦类孤子脉冲在时域和频域均具有真正的抛物线形状以及线性啁啾。展示了接近傅里叶极限的线性再压缩，使我们能够获得压缩因子为75的6皮秒压缩脉冲。
