Abstract
In this letter, we present beam quality improvement in a 50-W-class nonlinear chirped pulse amplification (NCPA) femtosecond all-fiber system. By exploring the group delay dispersion management, we manipulate the nonlinear spectrum broadening, which can not only alleviate the spatial deterioration caused by fundamental mode saturation, but also enable significant pulse compression under the influence of the soliton effect. This work offers insight into the design of the NCPA all-fiber laser system, providing guidelines on simultaneously realizing good beam quality and ultrashort pulses.
期刊介绍：
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
