Abstract
The high-performance gain-managed nonlinear amplification (GMNA) system benefits from the dynamic interaction between seeding pulses and the evolving gain spectrum, making it ideal for high-power, sub-50-fs fiber laser systems. In this work, we demonstrate a compact all-polarization-maintaining fiber GMNA system based on a stretched-pulse oscillator (SPO). The SPO directly generates high-energy, chirp-optimized pulses for subsequent GMNA, eliminating the need for additional pre-compressors and preamplifiers. By jointly optimizing both the seeding and amplification stages, this monolithic SPO-GMNA laser system enables efficient energy extraction and spectral broadening exceeding 100 nm, delivering 106.8-nJ and 31.8-fs pulses. This robust, high-peak-power femtosecond fiber laser holds significant potential for applications in biomedicine and advanced manufacturing.
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.
