Recent Advances in Fiber Laser Technology

Dear Colleagues,

Ultrashort pulse fiber lasers play critical roles in many applications such as high-precision machining, clinical surgery, attosecond science, space environment-based precision measurement, etc. This Special Issue addresses the advances in fiber lasers and their applications. Recent years have seen significant progress in the mode-locking techniques, saturable absorber materials, reduction in phase, intensity and common mode noise in fiber lasers. A number of cavity structures and amplifier designs with improved laser parameters including the pulse energy, average output power and integrated relative intensity noise and timing jitter were presented. Characteristics and parameters of the mid-IR and visible fiber lasers were also improved. The novel applications of femtosecond fiber lasers in building optical frequency combs with different spectral ranges, supercontinuum sources with high coherence and a nonlinear conversion-bridged tunable laser system which covers both the first and third biological windows were demonstrated. Novel papers in these research areas will be presented in the coming issue.

This Special Issue aims to introduce the recent advances in fiber laser technology. The topics of this Special Issue mainly cover the journal scope of nonlinear and ultrafast optics. Explicitly, papers relating to novel mode-locking techniques, fiber laser noise characterization and reduction techniques, high energy femtosecond pulse generation and amplification, fiber supercontinuum and their applications and biological window-covered tunable femtosecond fiber lasers are all welcome. Regular research articles, review articles and short letters are invited. All theoretical, numerical and experimental papers are accepted. This Special Issue, on one hand, will comprehensively summarize the recent development of fiber laser technology; on the other hand, we hope to predict and promote the future development of fiber laser technology.

In this Special Issue, original research articles and reviews are welcome. All theoretical, numerical and experimental papers are accepted. Research areas may include, but are not limited to the following:

• Novel mode-locked fiber lasers;
• Low-noise fiber lasers;
• Dual-comb fiber laser technique;
• Fiber laser-based optical frequency combs and their applications;
• Noise characterization and reduction in fiber laser system;
• Advanced high energy, femtosecond fiber laser system design and development;
• New energy scaling techniques in pulsed fiber lasers;
• Multi-core and multimode fiber lasers;
• Novel Mid-IR and visible fiber lasers;
• Tunable fiber lasers;
• Fiber supercontinuum and their applications;
• High-efficiency fiber laser-based nonlinear conversion techniques.

We look forward to receiving your contributions.
