Abstract

We demonstrate an improved layout of an all-polarization maintaining (PM) dispersion managed figure-9 ytterbium (Yb)-doped fiber oscillator with two distributed gain fibers. By adjusting the pump power of the two gain fibers, a stable pulse train with a repetition rate of 45.2 MHz and an average power of 104.17 mW can be obtained, corresponding to a pulse energy of 2.3 nJ. The output pulses can be de-chirped as short as 118 fs. The structural improvement increases the output pulse energy by more than three times compared to the conventional structural type with single YDF. In addition, the self-starting characteristics of the oscillator under different pumping conditions are experimentally studied. It is revealed that increasing the gain level of the NALM while reducing the absorption loss of the additional gain fiber is an effective way of achieving fast self-starting mode-locking driven by only one pump source. This work provides a new perspective for the design and development of figure-9 fiber lasers with high stability and high pulse energy.

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
