Abstract

To generate energetic short pulses from fiber laser oscillators in the 2-µm emission window, we here propose an alternative to the conventional methods of pulse stretching and dispersion management. We build a passively mode-locked fiber laser from anomalous single-mode fibers and utilize strong dissipative effects to delineate high and low pulse energy sections within the cavity. Whereas the main laser output delivers low-chirp sub-ps pulses with an energy up to 12 nJ, the intracavity pulse is reshaped into a ∼0.1-nJ conventional soliton, stabilizing the laser dynamics while enabling a wide tunability in both repetition rate and central emission wavelength.

2 微米能量管理孤子光纤激光器。
为了从光纤激光振荡器中产生 2 微米发射窗口内的高能短脉冲,我们在此提出了脉冲拉伸和色散管理等传统方法的替代方案。我们用反常单模光纤制造了一种被动模式锁定光纤激光器,并利用强耗散效应在腔体内划分出高、低脉冲能量区段。主激光输出提供能量高达 12 nJ 的低啁啾亚秒脉冲,而腔内脉冲则被重塑为 ∼0.1-nJ 的常规孤子,从而在稳定激光动态的同时,实现了重复率和中心发射波长的广泛可调谐性。

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.
