Abstract

We demonstrate the first 1 GHz fs erbium-doped fiber ring laser mode locked by nonlinear polarization evolution (NPE). The laser delivers a maximum average output power of 228 mW, correspondingly to single pulse energy of 0.228 nJ. The pulse spectral bandwidth is 32 nm, and the direct output pulse duration is 81.8 fs without extra-cavity compression. The measurement shows that the integrated relative intensity noise (RIN) and the residual root mean square phase noise are 0.0047 % (ranging from 1 Hz to 1 MHz) and 72 mrad (ranging from 10 Hz to 1 MHz), respectively. The result indicates that the high-repetition-rate lasers can provide competitive noise-related performances compared with other mode-locked erbium-doped fiber lasers. To the best of our knowledge, this represents the highest repetition rate achieved in a ring-cavity Er-doped fiber laser.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
