Abstract

We present a 2-μm all-fiber laser in which a highly chirped fiber Bragg grating (CFBG) sets the net cavity dispersion to -100.9 ps². Within an energy-managed laser architecture, this large anomalous dispersion enables the mode-locking of energetic and narrow-band pulses featuring: 17.8 nJ energy, 15.2 ps duration, and 0.36 nm bandwidth. These results validate that mode-locked laser oscillators incorporating CFBGs can generate picosecond pulses in the 2-μm wavelength region and demonstrate that, when combined with energy management, simultaneous scaling of pulse duration and energy is achieved. Experimental observations are well reproduced by numerical simulations.

高色散能量管理孤子光纤激光器。

我们提出了一种2 μm全光纤激光器，其中高啁啾光纤布拉格光栅（CFBG）将净腔色散设置为-100.9 ps2。在能量管理激光器架构中，这种大的异常色散使高能和窄带脉冲的模式锁定具有：17.8 nJ能量，15.2 ps持续时间和0.36 nm带宽。这些结果验证了采用CFBGs的锁模激光振荡器可以在2-μm波长区域产生皮秒脉冲，并证明了当与能量管理相结合时，可以实现脉冲持续时间和能量的同步缩放。数值模拟很好地再现了实验观测结果。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
